A hydrogen detection apparatus includes a hydrogen sensor, a sensor control circuit that senses the resistance value of the hydrogen sensor, and a microcomputer that sets an off time that differs depending on an operating environment and intermittently drives the sensor control circuit. The hydrogen sensor includes a first electrode; a metal-oxide layer disposed on the first electrode, and in which a resistance value changes in response to contacting hydrogen atoms; a second electrode disposed on the metal-oxide layer; and an insulating film that covers at least a portion of lateral surfaces of the first electrode, the metal-oxide layer, and the second electrode. A portion of at least one of (i) a first interface between the first electrode and the metal-oxide layer and (ii) a second interface between the second electrode and the metal-oxide layer is uncovered by the insulating film and exposed to a detection space.
