A temperature measurement device includes a first member forming a first claw at an end thereof and a second member forming a second claw at an end thereof. The second claw faces the first claw, and can move towards and away from the first claw. A spring is provided between the first member and the second member for generating force to move the second claw towards the first claw. A pair of thermal coupling wires is fixed on one of the first and second claws facing the other of the first and second claws. Thus an object needed to be measured can be arranged between the first and second claws and snugly engage the thermal coupling wires by the elastic force of the deformed spring.
