摘要： PROBLEM TO BE SOLVED: To provide a temperature detection device capable of invalidating abnormal detection without adding any dummy resistance different from a conventional case when a temperature detection element is not connected.SOLUTION: A temperature detection device 44, which is formed integrally with an overheat detection circuit 441 and a disconnection circuit 442 as an IC, includes a disconnection detection invalidation circuit 443 for invalidating the disconnection detection of a disconnection state detection circuit 442 when the voltage of a temperature sensitive diode connection terminal GH2 is larger than a disconnection invalidation threshold value Vth3 set larger than an overheat detection threshold value Vth1 and a disconnection detection threshold value Vth2. When a serially connected temperature sensitive diode 40h is not connected, a voltage larger than the disconnection invalidation threshold value Vth3 is applied to the temperature sensitive diode connection terminal GH2. Thus, when the temperature sensitive diode 40h is not connected, disconnection detection is invalidated without adding any dummy resistance different from a conventional case.
