To suppress an electric discharge while suppressing conventional possible disadvantages of an increase in a cost of a material or in a manufacturing, and an insulation deterioration due to a long-term deterioration.SOLUTION: In a plan view, a first conductor part A includes a convex corner part AC with a shape that a top part is rounded, and a second conductor part B includes a concave corner part BC opposite to the convex corner part AC. Extension lines of respective two lines forming an outline of the first conductor part A continuous to the convex corner part AC form together a convex corner. Extension lines of respective two lines forming an outline of the second conductor part B continuous to the concave corner part BC form together a concave corner. When a line passing through a top point aC of the convex corner and a top point bC of the concave corner is defined as "a corner line Lab", a cross point of the corner line Lab and the convex corner part AC as "a convex corner point aP", and a cross point of the corner line Lab and the concave corner part BC as "a concave corner point bP, "An inter-corner part distance Dp" that is a distance from the convex corner point aP to the concave corner point bP is longer than "an inter-corner distance Dc" that is a distance from the top point aC of the convex corner and the top point bC of the concave corner.SELECTED DRAWING: Figure 3 【課題】材料面や製造面でのコストアップや、経年劣化による絶縁性低下の懸念を抑えつつ、放電を抑制する。【解決手段】平面視で、第１導電部Ａが、頂部が丸められた形状の凸角部ＡＣを有すると共に、第２導電部Ｂが、凸角部ＡＣに対峙する凹角部ＢＣを有する。凸角部ＡＣに連続して第１導電部Ａの輪郭をなす２直線の延長線は、凸角をなす。凹角部ＢＣに連続して第２導電部Ｂの輪郭をなす２直線の延長線は、凹角をなす。以下では、凸角の頂点ａＣと凹角の頂点ｂＣとを通る直線を「角線Ｌａｂ」とし、角線Ｌａｂと凸角部ＡＣとの交点を「凸角部点ａＰ」とし、角線Ｌａｂと凹角部ＢＣとの交点を「凹角部点ｂＰ」とする。凸角の頂点ａＣから凹角の頂点ｂＣまでの距離である「角間距離Ｄｃ」よりも、凸角部点ａＰから凹角部点ｂＰまでの距離である「角部間距離Ｄｐ」の方が長い。【選択図】図３
