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.
