Abstract: Object:To provide a gas sensor having a small size and that can suppress gas detection problems caused by frost using only a small amount of power.Solution: A first electrode terminal (12) includes at least one first connection part (121) connected to a first wire and a first arm part (123) extending from the first connection part (121) to one end (11a) of a resistor (11). A second electrode terminal (13) includes at least one second connection part (131) connected to a second wire and a second arm part (133) extending from the second connection part (131) to the other end (11b) of the resistor (11). The first electrode terminal (12) and the second electrode terminal (13) are fixed to each other and form a water vapor diffusion cavity (S2) extending from the resistor (11) to a wiring member or the vicinity of the wiring member, with at least part of the first arm part (123) and at least part of the second arm part (133) coated with insulation.
