PROBLEM TO BE SOLVED: To provide a power supply device capable of saving a space for a thermistor wiring region and improving the insertion workability of a thermistor, and of preventing a tensile force of an electric wire for a thermistor from acting on the thermistor.SOLUTION: A power supply device 1 comprises: a battery assembly 2 that is an assembly of batteries 3 each having an electrode 4; and a battery coupling block body 10 having a case main body 11 provided on an electrode 4 side of the battery assembly 2 and provided with a plurality of terminal fixing parts 12 and 13 and a thermistor insertion part 20, an output terminal 32 and a coupling terminal 30 respectively fixed to the terminal fixing parts 12 and 13, and a thermistor 31 inserted into the thermistor insertion part 20 and detecting a temperature of the batteries 3. An electric wire W2 for a thermistor is withdrawn from the thermistor 31 in a direction along the thermistor insertion part 20, and the electric wire W2 for a thermistor is fixed to the case main body 11 by a binding band 35. |
