PURPOSE:To inhibit the short circuit of a flat-type electrochemical cell by coating the heat seal portion of each of two terminal materials with a heat seal resin and an adhesive electric-insulating coating material. CONSTITUTION:The heat seal portion of a terminal material 5 is coated with a coating material 7. Specifically, the portions of terminal materials 5 and 6 corresponding to heat seal sections (A) is precoated with a heat seal resin 14 and a thermoadhesive electric-insulating coating material 7. As long as the performance of reaction elements is not deteriorated, it is possible to apply the coating material 7 not only over the heat seal section (A) but also over the peripheral part of the cell or over the outside of the heat seal section (A). |
