Abstract
Disclosed is a ceramic heater and a ceramic plate for a ceramic heater, wherein, in order to prevent crack development at a ceramic surface around an electrode part and thereby improve durability, the end of a support part for an electrode rod is spaced apart from the ceramic surface opposite thereto, and a space for placing a filler mass is provided around the end of the support part for the electrode rod, whereby force or stress applied to the ceramic surface due to the expansion of the support part or by the filler mass is removed.
