A solar battery panel has at least: (a) a surface transparent protective plate; (b) an opto-electric conversion layer for constituting a solar battery; and (c) a bottom surface covering material. The surface transparent protective plate, the opto-electric conversion layer, and the bottom surface covering material are laid up in that order from a surface receiving photo-voltaics. A solar battery module consists of the solar battery panel and a macromolecular sealing frame member for sealing the peripheral edge portion of the solar battery panel. The sealing frame member consists of: (a) a top surface frame portion for filling around the peripheral edge portion of the solar battery panel at its top surface side and; and (b) a bottom surface frame portion for filling around the peripheral edge portion of the solar battery panel at its bottom surface side. The bottom surface frame portion is wider in width than the top surface frame portion.    Also claimed is the prodn. of the panel which comprises: (a) preparing a mould formed by mating a top surface mould with a bottom surface mould, where: (i) the top surface mould has an inner surface shape generally corresp. to the outer shape of the top surface side of the solar battery module and used for forming the top surface frame portion; and (ii) the bottom surface mould has an inner surface shape generally corresp. to the outer shape of the bottom surface side of the solar battery module and used for forming the bottom surface frame portion; (b) positioning and housing the solar battery panel in the mould so that a cavity may be formed around the peripheral edge; (c) injecting an organic compsn. in the cavity; (d) shaping and solidifying the organic compsn.; and (e) forming and mounting the sealing frame member on the peripheral edge portion of the solar battery panel.    ADVANTAGE -   Widening the bottom surface frame portion compared with the top surface frame portion provides the solar battery panel at its bottom surface side with a larger contact area with respect to the sealing frame member. The resulting sealing frame member has enhanced adhesive strength. Therefore, there is no separation of the sealing frame member from the solar battery module at its bottom surface side.
