NOVELTY - Sealing electrical element with transmission parts, comprises: (a) coating the thermosetting resin composite onto whole surface of the final lower surface of the upper sealing component; (b) splicing the upper sealing component and the lower sealing component together; and (c) heating the coalition formed by splicing so as to solidify the thermosetting resin composite.    USE - The methods , electrical element with transmission parts, and sealed thermosetting resin composite are useful for sealing electronic elements or optical elements (all claimed).    ADVANTAGE - The electrical element manufactured by the method, the luminous layer in the element and the whole side of the electrode are effectively protected, thus having excellent property of service life. Particularly, the thermosetting resin composite for sealing has low viscosity, thus having the advantages of capability of applying dripping-type injection technique, controllable coating amount and rapid coating.    DETAILED DESCRIPTION - Sealing electrical element with transmission parts, the electrical element with transmission parts. is formed by splicing a lower sealing component and an upper sealing component, where the sealing method comprises: (a) coating the thermosetting resin composite onto whole surface of the final lower surface of the upper sealing component to be spliced or the final upper surface of the lower sealing component to be spliced; (b) splicing the upper sealing component and the lower sealing component together so that the coating surface of the upper sealing component contacts the final upper surface of the lower sealing component or the final lower surface of the upper sealing component contacts the coating surface of the lower sealing component; and (c) heating the coalition formed by splicing so as to solidify the thermosetting resin composite. INDEPENDENT CLAIMS are:    (1) an electrical element with transmission parts, comprising: a lower sealing component; an upper sealing component that is separated from the lower sealing component and is located on the upper part of the lower sealing component; an electric device located between the lower sealing component and the upper sealing component; and a firming body layer of the thermosetting resin composite for splicing the upper sealing component and the lower sealing component; the firming body layer is filled between the bonding planes of the upper sealing component and the lower sealing component and is embedded with the electrical device; the firming body layer of the thermosetting resin composite becomes part or all of the transmission part; and    (2) a sealed thermosetting resin composite for sealing electronic elements or optical elements, comprising 25-90 pts.wt. of epoxide resin; 9-70 pts.wt. of thermal treating agent and 0.1-5 pts.wt. of treating accelerator; the thermosetting resin composite has a viscosity of 10-3000 cps at 25 degrees C.
