Zusammenfassung: | PURPOSE:To remove weak rigidity layers and impurities on a resin surface perfectly, and to improve the adhesion between terminal plates and an insulating thermal adhesive resin, by acid-treating the surface of the insulating thermal adhesive resin. CONSTITUTION:The surface of an insulating thermal adhesive resin 5 which consists of polypropylene-ethlene aceticacidvinyl copolymer, denatured polyester, or the like is treated by an acid such as a mixture acid of potassium dichromate and undiluted sulfuric acid, or the like. As a result, weak rigidity layers and impurities on the surface of the resin 5 which disturb the adhesion can be removed, to eliminate the presence of those materials at the contact surfaces between the insulating thermal adhesive resin 5, and the positive and negative terminal plates 2 and 4. Therefore, the effective adhesive area of the resin 5 is made larger, and a sufficient adhesion can be obtained. |
