Abstract
A pyroelectric detector includes a support member, a capacitor and a fixing part. The support member includes a first side and a second side opposite from the first side, with the first side facing a cavity. The capacitor includes a pyroelectric body between a first electrode and a second electrode such that an amount of polarization varies based on a temperature. The capacitor is mounted and supported on the second side of the support member with the first electrode being disposed on the second side of the support member. A thermal conductance of the first electrode is less than a thermal conductance of the second electrode. The fixing part supports the support member.
