    Abstract: PROBLEM TO BE SOLVED: To provide a variable gate field-effect transistor (FET) and an electrical and electronic apparatus including the same.SOLUTION: There are provided a variable gate FET designed to effectively suppress a problem of current reduction between a source and a drain of the FET due to heat while decreasing the temperature of the FET, and an electrical and electronic apparatus including the variable gate FET. The variable gate FET includes an FET and a gate control device that is attached to a surface or a heat generating portion of the FET and is connected in the circuitry to a gate terminal of the FET so as to vary a voltage of the gate terminal. A channel current between the source and drain of the FET is controlled by the gate control device varying the voltage of the gate terminal when the temperature of the FET increases above a predetermined temperature.
