A heater unit includes a pair of substrates formed from a polymeric foam and a cord-shaped heater sandwiched between the pair of substrates. The thickness of a region of each of the substrates at which the cord-shaped heater is disposed is thinned relative to other regions of the substrates in such a manner as to be shaped to the cord-shaped heater and thus the heater unit forms a flat shape. In the heater unit, the substrates are bonded together by an adhesive layer that is composed only from a pressure-sensitive adhesive.
