Abstract

See full text

A heater according to an embodiment includes a substrate that is formed of a heat resistant insulating material, a heating resistor that is provided on the substrate, a conductor that is provided on the substrate and that is electrically connected to the heating resistor, and a coating film that covers the heating resistor and the conductor. A plurality of groove portions are arranged on an end surface of the substrate along an outer periphery of the substrate, and a coefficient A=100×D/(T×P) satisfies 0.4≦A≦0.9 where T [μm] is the thickness of the substrate, D [μm] is the depth of the groove portion in a thickness direction of the substrate, and P [μm] is a pitch between the groove portions.
