An object of the present invention is to provide a ceramic heater so that hot spots around the end portions of a heat resistor may be prevented. A ceramic heater has a ceramic substrate having a mounting face for an object to be heated, a heat resistor 3 B embedded in the substrate and having end portions 3 a, and a connecting member 6 electrically connected with the end portion 3 a. At least one connecting member 6 substantially has an outer shape of a sphere, an ellipsoid of revolution, or a cylinder. The connecting member 6 has a fixing portion 3 a of the heat resistor by means of caulking.
