CERAMIC HEATER, GLOW PLUG, MANUFACTURING METHOD OF CERAMIC HEATER, AND MANUFACTURING METHOD OF GLOW PLUG
To dispose a resistor at a regular position inside of a substrate with higher accuracy.SOLUTION: In a ceramic heater, in a view of a pair of conductive parts (a first conductive part 121 and a second conductive part 122) in a lateral direction, tapered parts 131 and 132 each formed in such an outer shape that thickness in a vertical direction is reduced towards a rear end, are formed at a rear end side. The tapered parts 131 and 132 are configured in such a manner that an outer shape of the rear end forms an apex shape. A first tilt angle θ12 of an outer shape of a first outer edge which is positioned closer to one side of the vertical direction than the rear end, with respect to an axial direction is smaller than a second tilt angle θ22 of an outer shape of a second outer edge which is positioned closer to the other side of the vertical direction than the rear end, with respect to the axial direction.SELECTED DRAWING: Figure 6
【課題】基体内の正規の位置に抵抗体をより高精度に配置する。【解決手段】セラミックヒータは、一対の導電部（第１導電部１２１及び第２導電部１２２）を横方向からみたときに、それぞれの後端側に、上下方向の厚さが後端に向かうにつれて小さくなる外形形状をなす先細り部１３１，１３２が形成され、先細り部１３１，１３２は、後端の外形形状が頂点形状をなすように構成され、後端よりも上下方向一方側に位置する第１外縁の外形形状の軸線方向に対する第１傾斜角度θ１２が、後端よりも上下方向他方側に位置する第２外縁の外形形状の軸線方向に対する第２傾斜角度θ２２よりも小さい。【選択図】図６
