    Abstract: 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.

    Abstract: A seat heater includes a seating heater, a protection device of a non-resettable type, a base material, and a protecting heater. The protection device has a first surface and a second surface opposite to the first surface. The base material is a sheet having a first covering portion covering the first surface and a second covering portion covering the second surface, and is folded so that the first covering portion and the second covering portion face each other. The protecting heater heats the protection device. The protecting heater includes a pair of first heating portions and a second heating portion. The pair of first heating portions are formed as a meandered shape only on a surface, which faces the second covering portion, of the first covering portion. The second heating portion is disposed between the pair of first heating portions, and formed as a meandered shape both on the surface, which faces the second covering portion, of the first covering portion, and on a surface, which faces the first covering portion, of the second covering portion.
