Abstract
A planar heater includes a base, a resister pattern, a conductor pattern, a power supply electrode, and a base pattern. The base includes a surface portion made of an insulative material. The resistor pattern is on the base. The conductor pattern is on the base and electrically coupled to the resistor pattern. The power supply electrode is electrically coupled to the conductor pattern. The base pattern is on the base and made of a material different from a material of the surface portion of the base to print visible identification information.
