Claim 0:
1. A holding apparatus for holding a planar workpiece during an electrolytic plating treatment, the holding apparatus comprising:
a rear member; and
a front member connected to the rear member and having an opening part, the front member facing the rear member in a closed position,
wherein the planar workpiece is disposed between the rear member and the front member in the closed position so that the planar workpiece is at least partially exposed at the opening part,
the front member has a plurality of electrodes and a plurality of first insulating parts disposed along an edge part of the opening part in the width direction of the opening part,
the planar workpiece has a first surface that faces the front member in the closed position and is exposed at the opening part and a second surface that faces the rear member in the closed position,
the plurality of electrodes and the plurality of first insulating parts are configured to cover an edge part of the planar workpiece in a width direction of the planar workpiece,
the plurality of electrodes and the plurality of first insulating parts are configured to contact the first surface of the planar workpiece when held in the closed position,
the plurality of first insulating parts and the plurality of electrodes are arranged to extend along substantially an entire length of an upper or lower edge of the opening part of the front member, and
the first insulating parts and the electrodes are disposed, one after the other, along an edge of the opening part so that each of the electrodes is exposed to a plating solution during the electrolytic plating treatment.
