A power source stabilization circuit provided within a chip of an electronic device is provided. The power source stabilization circuit stabilizes a power source voltage supplied to an operational circuit of the electronic device. The power source stabilization circuit includes an amplifier that detects a fluctuation component in the power source voltage occurring in a main power source wiring used to supply the power source voltage to the operational circuit, amplifies the detected fluctuation component, and outputs the amplified fluctuation component, and a stabilization capacitor that is provided between an output end of the amplifier and the main power source wiring and supplies to the main power source wiring a current to reduce fluctuation in the power source voltage occurring in the main power source wiring, in accordance with the output from the amplifier.
