A part holder includes a part holding portion. In this part holding portion, a leadless part is held by a part receiving portion and an engaging piece. In such a state, the leadless part is inserted in a hole formed in a printed circuit board. At this time, a resilient piece provided on a leg of the part holder comes into abutment against an inner edge of the hole, whereby the part holder is fixed by the hole. Also, the part inserted in the hole is urged onto one surface of the hole by a resilient portion of the part holder. Thus, a pattern formed on one main surface of the part is closely contacted with a pattern formed on a backside of the printed circuit board.
