PROBLEM TO BE SOLVED: To provide a temperature detector in which the temperature of a solid-state-image pickup element can be accurately detected, and to provide a method, and also to provide a temperature control device in which cooling efficiency is improved by feedback-controlling a temperature of a solid-state-image pickup element on the basis of the detected temperature of the solid-state-image pickup element, and a method. SOLUTION: In view of the fact that a potential difference between a base and an emitter of a transistor 24 has the temperature dependency, the potential difference between the base and the emitter of the transistor 24 mounted on the solid-state-image pickup element 21 is detected via external terminals which are respectively short-circuited, and temperature information is generated according to the detected potential difference.
