摘要： A sheet heater comprises a sheet form heating unit configured from a wire heater. The heating unit comprises a first heating unit positioned along a peripheral edge of the area subject to heating, and a second heating unit positioned at an area surrounded by the first heating unit. The second heating unit comprises a plurality of meandering parts, with mutually adjacent meandering parts overlapping each other in the meandering direction. In the heating unit, the width (WL) of the wire heater is greater than the width (WP) between mutually adjacent wire heaters.

摘要： Conventional heater units have a problem in that both ventilation characteristics and mechanical strength cannot be satisfied at the same time. A heater unit includes a base material and a cord-shaped heater, the cord-shaped heater being disposed on and fixed to the base material, in which the base material is made by combining a structural yarn that is disposed in an approximately planar shape and a nonwoven fabric with each other, and the cord-shaped heater is fixed in direct contact with the structural yarn.

摘要： 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.
