Abstract (en)
A ceramic heater 2 is arranged in a metallic cylinder member 3 by forming a convergent taper portion 2t at the leading end 2a of the ceramic heater 2 and by positioning the leading end 3a of the metallic cylinder member 3 on the leading end side of a taper starting point P1 of the taper portion 2t. Solder is applied in the clearance between the inner circumference 3d of the metallic cylinder member 3 and the outer circumference 2b of the heater 2. A solder layer 10 applied is made to exist on the leading end side of the taper starting point P1 of the taper portion 2t, too. The thick solder layer 10 existing on the leading end side performs the action of preventing a cut or broken off portion of the ceramic heater from separating or sliding out.
