However, in the above configuration, it is difficult to form a thick resin layer, and the surface to be coated has irregularities, resulting in uneven film thickness and low withstand voltage between the positive and negative terminals and with the back member. In addition, the conductive adhesive fills the pinholes formed on the resin coated surface, causing a short circuit with the positive electrode. The adhesive strength between the lead wire or relay auxiliary terminal and the electrode is weak. Metal is used as the back member for humidity control reasons, but it requires a space between the electrode surface and the back member in order to obtain sufficient insulation from the solder portion 10 and the conductive adhesive 7, resulting in disadvantages such as the module becoming thicker. had.
