Provided is a heater unit (31), formed from a pair of substrates (10, 10') further formed from a polymer foam, and a cord-shaped heater (1) which is disposed sandwiched between the pair of substrates (10, 10'). The locations in the substrates (10, 10') whereat the cord-shaped heater (1) is disposed are made thinner so as to conform to the shape of the cord heater (1) and thus form a flat shape. In the heater unit (31), the pair of substrates (10, 10') is bonded by bonding layers formed only from an adhesive.
