BATTERY PACK CASE AND METHOD FOR MANUFACTURING SAME, AND BATTERY PACK AND METHOD FOR MANUFACTURING SAME

摘要

A thin-wall portion can be formed while securing fire retardancy and restrictions on shapes of a battery pack case can be removed. A battery pack case includes a first case component 21 and a second case component 22 having a region coupled to the first case component 21. A space for housing a battery is formed by coupling the first case component 21 and the second case component 22 with each other. The first case component 21 and the second case component 22 respectively include a first resin portion 25 constituted by a fire-retardant resin film and a second resin portion 26 in which, while retaining a predetermined region of the first resin portion 25, resin is integrally molded at a region of the first resin portion 25 which differs from the predetermined region.
