    • There are provided a ceramic heater in which a defect, such as generation of a gap at the interface between an insulating substrate and a heat-generating resistor, is unlikely to occur in the course of manufacture or use, and a glow plug using the ceramic heater. A ceramic heater 110 includes an insulating substrate 111 extending in the direction of an axis AX and a heat-generating resistor 115, which has a heat-generating portion 116, two lead portions 117, 117 and two lead lead-out portions 118a and 118b. The ceramic heater 110 satisfies an expression S1≦0.34 Sa, where Sa is the area of a cross section of the ceramic heater 110 taken perpendicular to the direction of the axis AX, and S1 is the total cross-sectional area of the two lead portions 117, 117 as measured in the cross section.
    • 提供了一种陶瓷加热器,其中在制造或使用过程中不可能发生缺陷,例如在绝缘基板和发热电阻器之间的界面处产生间隙,以及使用陶瓷的电热塞 加热器。 陶瓷加热器110包括沿轴线AX延伸的绝缘基板111和发热电阻115,发热电阻115具有发热部分116,两个引线部分117,117和两个导线引出部分118a和118b 。 陶瓷加热器110满足表达式S1≦̸ 0.34Sa,其中Sa是垂直于轴线AX方向截取的陶瓷加热器110的截面面积,S1是两个引线部分的总横截面面积 117,117在横截面中测量。
