Abstract

PURPOSE:To obtain high output with a peak retaining time of rush current shortened by inserting at least two positive characteristic thermistor elements in the hollow part of a heat release body in the state where a terminal plate is held between the elements mentioned above, and making one main surface of a thermistor to thermally contact the inner wall of the hollow part facing a heat release fin. CONSTITUTION:Plural heat release fins 2 and 4 are formed on the upper and the lower surfaces of a heat release body 1 composed of a stick state hollow metallic body, and a terminal plate 9 is composed of a elastic metallic plate formed in a wave plate state. The peak retaining time of rush current can be shortened with a space part arising between the terminal plate and positive characteristic thermistor elements, with the heat dissipation of the positive characteristic thermistor elements facing the space part worsened, and with a resistant value made to increase with a temperature immediately after electrification made to quickly arise, because the two positive characteristic thermistor elements 7 and 8 are inserted in a hollow part of the body 1 in the state where the plate 9 is held between these elements, and are orthogonally mounted to a wind direction in the inside of a hot air heater device.
