Abstract
A pyroelectric-type infrared sensor is provided with: a sensor element; a shield case for covering the sensor element; an infrared transmission filter; an output circuit, which performs impedance conversion to output signals of the sensor element and outputs the signals; and at least one reflecting film. In the pyroelectric-type infrared sensor, the at least one reflecting film, which reflects infrared, is provided between the infrared transmission filter attached to the shield case and surface electrodes, and the infrared transmission filter is disposed extremely close to the surface electrodes.
