摘要:
There is disclosed a ceramic heater 11 comprising: a plate member 12 made of insulating ceramics in which one or more pair(s) of through-holes 13 are formed; a conductive layer 19 made of conductive ceramics; and a coating layer 21 made of insulating ceramics; wherein a joint member 14 made of conductive ceramics is inserted into the through-hole; an end face 16 of the joint member has a same plane with a main surface 15 of the plate member; the joint member is coated with the conductive layer 19 and thereby fixed to the plate member and also connected with the conductive layer having a heater pattern 20; and an opposite side of the joint member projects from the plate member and the projecting portion 18 constitutes a terminal on which the coating layer is not formed. There can be provided a ceramic heater by which an object to be heated being put directly thereon can be heated uniformly and of which heating efficiency is high and in which the heater main body is not large in size and is compact and scattering of impurities or particles is small and which has a long operating life and is inexpensive.
