Abstract:
1. A battery pack attached to an electronic apparatus for supplying a power thereto, comprising: an exterior housing for covering entirety of said battery pack; a plate-shaped resin-formed body positioned and held in place on an inner wall surface of said exterior housing to divide an internal space defined by said exterior housing into at least two internal spaces in a thickness direction thereof; a battery received in a first internal space provided by said resin-formed body to output said power; and a wiring substrate held in place by said resin-formed body in a second internal space provided by said resin-formed body, and having a control circuit for controlling a supply of said power from said battery, said control circuit being mounted on said wiring substrate, wherein, said exterior housing allows a relay wiring substrate at least having a terminal for outputting said power to be held in place so as to be in close contact with the inner wall surface of said exterior housing such that said terminal is exposed to the outside of said exterior housing, said relay wiring substrate has at least one metal sheet-like wiring material provided on one of its longitudinal ends, which extends towards the wiring substrate along the thickness direction, said wiring substrate has a sheet-shaped wiring material, which extends from the wiring substrate towards the relay wiring substrate along the thickness direction, said relay wiring substrate is electrically connected to said wiring substrate separately by both the metal sheet-like wiring material and the sheet-shaped wiring material independently of each other, and said battery allows said terminal to output said power through said wiring substrate, said metal sheet-like wiring material and said relay wiring substrate sequentially.
