<p>Provided is a ceramic resistor that is capable of immediately shutting power off in the event of generation of abnormal heat in the resistor without requiring a thermal fuse to be added. The ceramic resistor (11) is provided with: a resistor body (1) which is created by means of sintering of a mixture of a conductive material and insulating ceramics; a pair of electrodes (2) which are fitted to either end of the resistor body (1) in the length direction; and lead terminals (4) which protrude outward from the respective electrodes (2). A conductive metal film (3) having a lower resistivity than that of the resistor body (1) is provided along the entire circumference of the outer peripheral surface of the resistor body (1) in a partial region away from the electrodes (2).</p> |
