摘要： Disclosed is a ceramic heater capable of preventing failures due to the thermal stress, such as cracks, and corrosion by a calcium component. The ceramic heater has a heating element including at least one substance selected from silicides, nitrides and carbides of molybdenum and silicides, nitrides and carbides of tungsten as a main component, and a base mainly containing silicon nitride in which the heating element is embedded, wherein the base includes: a rare earth element component in an amount from 4 to 25% by mass in terms of an oxide thereof; a silicide of chromium in an amount from 1 to 8% by mass in terms of chromium silicide; and an aluminum component in an amount from 0.02 to 1.0% by mass in terms of aluminum nitride.

摘要： A ceramic heater (12) includes a substrate (60) and a resistor element (30) buried in the substrate (60). The resistor element (30) includes a heat-generating portion (33), lead portions (31), and intermediate portions (40) located between the heat-generating portions (33) and the lead portions (31). The intermediate portions (40) are formed such that, when cross sections at arbitrary two points P1 and P2 along the axis XA direction are compared, both the diameter CL of an imaginary circumscribed circle CG containing cross sections of the resistor element 30 and the total cross sectional area HS of the cross sections become small in the front end side cross section as compared with those in the rear end side cross section.
