Abstract:
1. A protection circuit module for a secondary battery, comprising: a wiring substrate comprising a top surface, a back surface opposite the top surface, and cutout or through-hole in the wiring substrate; two battery-side external connection terminals provided on the top surface of the wiring substrate; multiple load-side external connection terminals provided on the back surface of the wiring substrate opposite the top surface; one or more electronic components provided on the wiring substrate; and two metal plates provided on the respective battery-side external connection terminals, wherein the cutout or through-hole is provided at a portion of the wiring substrate in which one metal plate of the two metal plates is provided, the one metal plate is provided is on a corresponding battery side external connection terminal of the two battery side external connection terminals, and the corresponding battery side external connection terminal is interposed in a thickness direction of the wiring substrate between the wiring substrate and a portion of the one metal plate, so that a first part of the one metal plate over a top surface side of the wiring substrate is exposed through the cutout or the through-hole when viewed from the back surface of the wiring substrate.
