A thermistor includes a thermistor body and terminal electrodes disposed at both ends of the thermistor body. A first lead is longer than a second lead. The first and second leads include tips having inclined shapes that are cut such that metal lines are surface-exposed, respectively. The thermistor body is attached at a predetermined side position of the first lead such that the first lead and a side folding portion of the terminal electrode form a predetermined angle θ. The terminal electrode and the first lead are connected to each other through solder, and the second lead and the terminal electrode are connected to each other through solder. This can prevent the occurrence of damage even if an excessive thermal stress is applied. The temperature sensor with leads having stable electric connection with the temperature sensor that has satisfactory detection sensitivity and high reliability is achieved.
