1. A state estimation system comprising:
a thermal load detection unit configured to detect a thermal load of an object; and
an estimation unit configured to estimate a state of the object based on the thermal load of the object detected by the thermal load detection unit,
wherein the thermal load detection unit includes:
a thermoelectric generation module configured to generate electric power by a temperature difference between a temperature of the object and a temperature around the object,
a power storage unit configured to store electric charge generated from the thermoelectric generation module, and
a transmission unit configured to be driven by discharge from the power storage unit.
