To provide an isolator capable of reducing a likelihood of breakdown that occurs.SOLUTION: An isolator includes: a first electrode; a first insulating portion provided on the first electrode; a second electrode provided on the first insulating portion; a second insulating portion provided around the second electrode, along a first plane perpendicular to a first direction from the first electrode toward the second electrode, the second insulating portion in contact with the second electrode; and a first dielectric portion provided on the second electrode and the second insulating portion. The second electrode includes a bottom surface facing the first insulating portion, an upper surface facing the first dielectric portion, a first side surface connected to the bottom surface, and a second side surface connected to the upper surface and the first side surface. The upper surface is wider than the bottom surface in a second direction along the first plane, and the second direction is from a center of the second electrode toward an outer edge of the second electrode. The first side surface is tilted with respect to the bottom surface and the second side surface.SELECTED DRAWING: Figure 3 【課題】破壊が生じる可能性を低減可能なアイソレータを提供する。【解決手段】アイソレータは、第１電極と、前記第１電極の上に設けられた第１絶縁部と、前記第１絶縁部の上に設けられた第２電極と、前記第１電極から前記第２電極に向かう第１方向に垂直な第１面に沿って前記第２電極の周りに設けられ、前記第２電極に接する第２絶縁部と、前記第２電極および前記第２絶縁部の上に設けられた第１誘電体部と、を備える。前記第２電極は、前記第１絶縁部に対向する底面と、前記第１誘電体部に対向する上面と、前記底面につながった第１側面と、前記上面および前記第１側面につながった第２側面と、を有する。前記第１面に沿って、前記第２電極の中心から前記第２電極の外縁に向かう第２方向において、前記上面は、前記底面よりも広く設けられ、前記第１側面は、前記底面および第２側面に対して傾斜する。【選択図】図３
