A heater component has a substrate part and a thin coating heater which is equipped outside this substrate part and generates heat by power supply. The thin coating heater is formed of a thermal sprayed coating. The thin coating heater has a heater body and a heater extension part. The heater body is arranged on a first end face of the substrate part. The heater extension part is extended from the heater body to a second end face of the substrate part through a side surface of the substrate part. A tip part of the heater extension part is a heater power supplying part for supplying electric power to the heater body.

Heater component

The heater component () has a substrate part (), and a thin coating heater () which is equipped outside this substrate part () and generates heat by power supply. The thin coating heater () is formed of a thermal sprayed coating. The thin coating heater () has a heater body () and a heater extension part (). The heater body () is arranged on a first end face () of the substrate part (). The heater extension part () is extended from the heater body () to a second end face () of the substrate part () through a side surface () of the substrate part (). A tip part () of the heater extension part () is a heater power supplying part () for supplying electric power to the heater body ().

Provided is a heat generating component of which volume resistivity hardly varies even if used repeatedly at a high temperature for a long period of time. Since a thin coating heater part () formed on a substrate part () is composed of a thermal sprayed coating containing TiO(wherein, 0&#x3c;y/x&#x3c;2.0 is satisfied), obtained is a heat generating component () having volume resistivity which is suitable for a heater and hardly varies even if prescribed temperature change and temperature keeping are repeated.
