摘要

A battery pack comprises a molded resin portion which holds a part of or the whole of battery inserted thereto, and an externally exposed output terminal. The battery pack further comprises an insulating block which is provided with a breaker mechanism for cutting-off current flow when an over-current flows. The insulating block is held by being inserted in the molded resin portion. The insulating block holds the output terminal on its surface. The output terminal held by the insulating block is held at a prescribed position so as to be externally exposed from the molded resin portion.
