<p>[Problem] To provide a protective circuit module that can reduce production costs while maintaining high heat transfer between electronic elements that are sources of heat and a heat-sensitive element that detects that heat and to provide a battery pack provided with the same. [Solution] A substrate is formed from insulating layers inserted between metal wiring layers (140b1, ...) and these same metal wiring layers (140b1, ...). When the substrate, FET elements (142, 143), and a thermistor element (144) are viewed in a planar view in the direction of the Z axis, part of the metal wiring layer (140a2) is formed on the substrate in a state that overlaps part of the FET elements (142, 143) and all of the thermistor element (144). The thermistor element (144) detects the temperature of the FET elements (142, 143) via the metal wiring layer (140a2).</p> |
