Abstract
A seat heater according to the present invention includes: a heater that is provided between a seat cushioning material and a seat trim cover and includes a heating wire laid on a base material; a temperature detection unit provided in the vicinity of the heating wire of the heater; and a temperature control unit configured to control a temperature of the heater so that it approaches a target temperature, in which the temperature control unit calculates an estimated environment temperature, which is an estimated value of a temperature around the temperature detection unit, based on a rate of increase of a temperature indicating an amount of change of the temperature detected by the temperature detection unit in a period after an elapse of a predetermined time from a start of heating the heater, and corrects the target temperature so that it becomes lower as the estimated environmental temperature becomes lower.
