Abstract: An insulating support includes a pillar-shaped portion made of resin, a metal insert buried in one end surface of the pillar-shaped portion in an axial direction, a metal insert buried in the other end surface of the pillar-shaped portion in the axial direction, and one protrusion made of the resin and provided in a ring shape and integrally with the pillar-shaped portion on an outer circumferential surface of the pillar-shaped portion on a side of the metal insert. The metal insert includes a first cylindrical base portion and a first distal end portion. The metal insert includes a second cylindrical base portion and a second distal end portion. A whole of the first distal end portion is disposed within an extended range of the protrusion in the axial direction.
