<p>Disclosed is a circuit for detecting static electricity, wherein a switch for cancelling charges on an electrode body that detects static electricity is not necessarily provided. The circuit (30) for detecting static electricity is provided with: a P-channel FET and an N-channel FET having respective gates thereof electrically connected to each other; a direct-current power supply for driving the P-channel FET and the N-channel FET; a portion where the gates of respective P-channel FET and the N-channel FET are electrically connected to each other, as an electrostatically charging section (39) to be electrostatically charged; and automatically resetting means (C1, C2) which make the electrostatically charging section (39) automatically discharge the static electricity, with which the electrostatically charging section has been electrostatically charged, and make it possible to have the electrostatically charging section (39) electrostatically charged again.</p> |
