Claim:
1. A connection structure between metal plates, comprising: a first metal plate having an insertion hole formed therein, the insertion hole having an inner surface at least part of which being formed as a cylindrical inner wall surface curving along an arc; and a second metal plate having a contact portion which is inserted into the insertion hole, so as to relatively position the first metal plate and the second metal plate and put the contact portion into contact with the cylindrical inner wall surface to electrically connect the first metal plate and the second metal plate, wherein: the contact portion is made of a curved blade plate curving with a curvature smaller than that of the cylindrical inner wall surface in a same direction as that of the cylindrical inner wall surface; and the curved blade plate is pressed into the insertion hole while being elastically deformed in a curving direction so that edges along both side edges of a single curving outer peripheral surface thereof each bite into the cylindrical inner wall surface and make press contact with the cylindrical inner wall surface, wherein a distance between the side edges of the single curving outer peripheral surface of the curved blade plate where a horizontal width between the side edges is the largest is longer than a diameter of the insertion hole.
