NOVELTY - The method involves preparing (100) a flange face that is used as opposing surface of a flange portion. The flange face with a groove portion is provided to oppose (102) a flanged heat resistant glass cylinder portion. A slurry-like adhesive agent is provided with a silicon-di-oxide micro-particle into the groove portion to form (104) a zygote. The zygote is heated (106) at temperature of 100 degree Celsius or more to attach flange portions of joined flanged heat resistant glass cylinder portion.    USE - Manufacturing method of flanged heat resistant glass cylinder portion stacking structure of flanged heat resistant glass container (all claimed) for heat-processing solar cell and organic electroluminescent large substrate.    ADVANTAGE - The flanged heat resistant glass cylinder portion stacking structure can be provided with outstanding dimensional accuracy. Thus, the flanged heat resistant glass container can be enlarged. The large sized heat resistant glass container can be provided with outstanding gas-seal property easily. The redundancy in the flanged heat resistant glass cylinder portion stacking structure can be avoided. The manufacture of the heat resistant glass container can be obtained compactly and easily. The illumination intensity of organic electroluminescent illumination can be maintained precisely, without deterioration of the organic electroluminescent component.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a manufacturing method of flanged heat resistant glass container;    (2) a flanged heat resistant glass cylinder portion stacking structure;    (3) a flanged heat resistant glass container;    (4) a manufacturing method of heat-resisting- glass element bonded-structure portion; and    (5) a heat-resisting-glass element bonded-structure portion.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating manufacturing method of flanged heat resistant glass cylinder portion stacking structure. (Drawing includes non-English language text)    Step for preparing flange face that is used as opposing surface of flange portion (100)    Step for opposing flange face with flanged heat resistant glass cylinder portion (102)    Step for forming zygote (104)    Step for heating zygote at specific temperature to attach flange portions of joined flanged heat resistant glass cylinder portion (106)
