Abstract
A pinching detection device for detecting that an object has been pinched in an opening/closing apparatus. The device includes a sensor having temperature dependence and detecting that an object has been pinched, based on a frequency element and a magnitude of an output signal; a filter portion for extracting a signal in a predetermined frequency band, from an output of the sensor; and an amplification portion for amplifying the extracted signal. In this device, the frequency band and an amplification factor of the amplification portion is determined in response to an ambient temperature.
