Thermal detector, thermal detection device, and electronic instrument

A thermal detector comprising:

• a thermal detection element that changes physical characteristics according to temperature;
• a light-absorbing member configured and arranged to collect heat and to transmit collected heat to the thermal detection element, the light-absorbing member being 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;
• a support member including a first side and a second side opposite from the first side with the thermal detection element being mounted on the first side and the second side facing a cavity, and the thermal detection element being disposed between the support member and the light-absorbing member;
• and
• a support part supporting and linking to a portion of the second side of the support member.
