<p>The invention provides a ceramic heater that makes the temperature of a ceramic substrate uniform by suppressing the transfer of heat from the ceramic heater to a housing. The ceramic heater includes a heater formed on or under the surface of a ceramic substrate, and the surface roughness on the side of the ceramic substrate is JIS B 0601 Rmax=0.1-200 νm.</p> |
