PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module that allows continuous use even when a disconnection state partially occurs. SOLUTION: When a disconnection state occurs in a thermoelectric conversion module, a voltage higher than that of during the normal time is applied to a current path switching part 140 connected to both ends of a thermoelectric-device group including the disconnection part. Thus, a current is made to flow in a wire 430 via a zener diode 441, and finally, the wire 430 is melted down. If the wire 430 is melted down, a movable part 421 of a switch 420 is moved to an on-state position by biasing-force of a spring 450 so as to make the switch 420 in an on-state. When the switch 420 is in an on-state and both ends of the thermoelectric-device group including the disconnection part is short-circuited, a current path that does not pass the disconnection part is formed. Consequently, even if a disconnection state partially occurs in the thermoelectric conversion module, parts other than the specific thermoelectric-device group including the disconnection part can be continuously used as they are.
