Pyroelectric detector, pyroelectric detection device, and electronic instrument

摘要

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. The fixing part supports the support member, with the cavity being formed between the support member and the fixing part.
