The internal space of the case is divided into first housing portions and a second housing portion separated from the first housing portions by a partitioning wall. A positive characteristic thermistor element is housed in the second housing portion. At least two terminal members are provided, each with a contact terminal portion, a conductive portion and a lead-out terminal portion. The contact terminal portions are positioned in the second housing portion each in contact with one of the electrodes of the positive characteristic thermistor element. The conductive portions are electrically continuous to the contact terminal portions and are led to the first housing portions through the partitioning wall. The lead-out terminal portions positioned in the first housing portions, are electrically connected to the conductive portions and led out to the outside at the first housing portions. The second housing portion, where the positive characteristic thermistor element is positioned, is cut off from the atmospheres in the first housing portions.

Positive characteristic thermistor device

A PTC thermistor device including a PTC thermistor element of a circular configuration, and a casing made of a plastic material. The casing has a substantially parallelepipedic body portion and a projecting portion having a pair of parallel side surfaces and a planar top surface. A terminal fitting is provided in contact with the PTC element and has plug portions projecting from the casing at the opposite sides of the projecting portion. The plugs has projecting lengths which are not higher than the height of the projecting portion of the casing.
