Seat heater and seat cover having the seat heater

摘要

A substrate (6) comprises a base material (6) and a heater wire (7) arranged on the base material (6). The base material (6) is a base material (6) having a cut portion (9) (8) protruding from the side wall (6a). The heater wire (7) is disposed, and the base portion (8 b) of the folded-back portion (8) is folded back toward the base (6) side while the folded portion (8) Is positioned inside the edge (6a) of the base material (6). Thereby, it is possible to realize the seat heater (5) without lowering the temperature rise performance.
