Patent ID: 7854975

Claim:
A ceramic heater, comprising: a base ceramic member having a resistance heating element embedded therein; a tubular ceramic member; a single joining layer having a thickness of 0.05 to 0.3 mm, and which joins the base ceramic member directly to the tubular ceramic member; and feeder members disposed inside said tubular ceramic member for supplying power to the resistance heating element, wherein the single joining layer comprises an aluminum alloy containing 9.0 to 10.5 wt % silicon, 1.0 to 2.0 wt % magnesium, no more than 0.8 wt % iron, no more than 0.25 wt % copper, no more than 0.10 wt % manganese, no more than 0.20 wt % Zn and no more than 0.15 wt % of any other element aside from aluminum, with the maximum amount of each such other element being no more than 0.05 wt % and with aluminum being the balance of the composition, and directly joins the base ceramic member and the tubular ceramic member to each other by being thermally compressed at a joining temperature that is equal to or higher than a temperature obtained by subtracting 30° C. from a solidus of the aluminum alloy and lower than a liquidus of the aluminum alloy.
