Abstract: PURPOSE:To enable safe and handy detection of gas by a method wherein hydrogen is released from a hydrogen-occluded metal by a heating means to a gas detector responding to a hydrogen gas and the resistance value is detected with a detection circuit to send a signal. CONSTITUTION:A gas detector 1 is provided with a gas detection unit 3 and a hydrogen releasing unit 4 having a hydrogen-occluded metal 42 and a heater 43 on a base housing a detection circuit, a signal transmission circuit and the like.
