Temperature measurement module and power storage module

A temperature measurement module for measuring the temperature of a temperature measurement target, the temperature measurement module comprising:

• a flexible printed circuit board that includes an insulating sheet member and a circuit pattern routed in the sheet member;
• a temperature sensor attached to the flexible printed circuit board;
• and
• a heat transfer member thermally fixed to the temperature sensor,
• wherein the sheet member includes a through hole located outward of a region overlapped with the temperature sensor,
• the heat transfer member includes a heat receiving portion that is arranged in the sheet member through hole and is configured to receive heat from the temperature measurement target,
• the temperature measurement module further comprises:
• a reinforcing plate arranged on a temperature measurement target side of the flexible printed circuit board,
• the reinforcing plate includes a reinforcing plate through hole that is in communication with the sheet member through hole, and the heat receiving portion is arranged inside the reinforcing plate through hole, and
• the heat receiving portion is provided so as to fill the space in the sheet member through hole and the reinforcing plate through hole, and a lower end of the heat receiving portion is formed at a position conforming to a lower surface of the reinforcing plate.
