摘要： A first plate-like portion is provided with a plurality of first holes extending therethrough in a central axis direction. A second plate-like portion is provided with a plurality of second holes extending therethrough in the central axis direction. The plurality of first holes, the plurality of second holes, a first notch and a second notch overlap one another, to thereby form a flow path which connects one side and the other side of each of a plurality of insulating plates and through which insulating oil can flow in a first direction.
