An image signal amplifying circuit comprises: an amplifier circuit for amplifying an image signal; an output capacitor and a resistance, both being serially connected between an output node of the amplifier circuit and an output terminal; and a second-order high pass filter having a value of Q larger than one, the second-order high pass filter being provided at a preceding stage of the amplifier circuit, wherein distortion to correct a sag arising in a high pass filter on an output side, the high pass filter including the output capacitor and the resistance, is caused in the input image signal by a characteristic of the second-order high pass filter.
