A PTC device is provided which is capable of surely functioning as the PTC device even in a wiring through which a large current flows. A combined PTC device ( 10, 10 ') is composed of two PTC devices respectively comprising a lamellar PTC element ( 12, 12 ') which is composed of a polymeric PTC material and a pair of electrodes ( 14,16 ; and 14',16' ) which are arranged apart from each other on one side of the PTC element. The electrodes ( 14, 16 ) of one PTC device are respectively opposite to the electrodes ( 14', 16 ') of the other PTC device, and terminals ( 20, 21 ) are arranged between the respective opposite electrodes. The respective opposite electrodes and the terminal between them are electrically connected with each other.
