The invention discloses an electric field detector based on a CMOS6 NOT gate, which comprises an electrostatic detector and an audio electric field detector. The electrostatic detector and the audio electric field detector detect a first NOT gate of a CMOS6 NOT gate integrated circuit as an electric field, and the rest five NOT gates are inverting amplifiers with stable neutral-point potential; and an input end of the first NOT gate is connected with a probe. A second NOT gate of the electrostatic detector is used for pre-amplification, a third NOT gate and a fourth NOT gate of the electrostatic detector are connected in parallel and used as output drive, and a fifth NOT gate and a sixth NOT gate of the electrostatic detector are connected in parallel and matched with resistors with the same resistance value to form a phase inverter of which gain is 1; a second NOT gate, a third NOT gate and a fourth NOT gate of the audio electric field detector form an inverting amplifier of which gain ...
