である。(Function) With the configuration of the present invention, the purpose of the pyroelectric infrared detector assembled as a component on the board 4 is to input and detect infrared rays mainly generated from the human body. Detecting the ambient temperature conducted through the metal case on the side of an infrared detector has a high possibility of causing a false alarm, and may lead to instability of the detector itself. Therefore, the ambient temperature is conducted from the side metal case of the conventional pyroelectric infrared detector, eliminating unnecessary temperature detection that is detected by the internal element 6, In order to improve reliability without compromising performance, the metal case that covers the sides of the pyroelectric infrared detector is covered with an insulating cap that has relatively poor conductivity for heat sources. The required amount of infrared rays is inputted from the light receiving port on the front of the infrared detector, and the accurate detection function of the pyroelectric infrared detector is generated.
