Abstract
The present invention provides a heater including an insulating base made of ceramic, and an electrically conductive line embedded in the insulating base. The electrically conductive line contains electrically conductive grains and ceramic grains. The average grain size of the ceramic grains in the electrically conductive line is smaller than the average grain size of the ceramic grains in the insulating base.
