A thermal detector has a thermal detection element in which a physical characteristic changes based on temperature, a light-absorbing member configured and arranged to collect heat and transmit collected heat to the thermal detection element, a support member mounting the thermal detection element on a first side with a second surface facing a cavity, and a support part supporting a portion of the support member. The light-absorbing member is a plate shaped member at least partially contacting a top part of the thermal detection element and having a portion overhanging to an outside from the top part of the thermal detection element in plan view. |
