Abstract
Disclosed herein is a manufacturing method for a ceramic heater. The manufacturing method includes the step of manufacturing a sintered ceramic substrate using a ceramic material and forming a conductive through hole in the ceramic substrate, the step of screen printing low temperature firing paste on the ceramic substrate, thus forming a heating wire, the step of screen printing Ag paste on the through hole, thus forming an electrode, the step of joining, using heat and pressure, a green sheet to a surface of the ceramic substrate on which the heating wire is formed, the step of firing the joined ceramic substrate and green sheet at low temperature, thus manufacturing a substrate body, and the step of brazing the lead wire to the electrode of the substrate body using filler metal while the lead wire is exposed to atmosphere.
