A seat heater mounted to a seat includes: a heating wire; a base material provided with the heating wire and having air permeability; an excessive temperature rise prevention element that prevents an excessive temperature rise of the heating wire; and an auxiliary heating wire that heats the excessive temperature rise prevention element, in which air permeability in an auxiliary heater area provided with the auxiliary heating wire is lower than air permeability in a heater area provided with the heating wire, so that heat dissipation in the auxiliary heater area is suppressed to enable a temperature of the excessive temperature rise prevention element to rise efficiently to follow the temperature rise of the heater area.
