Claim:
A wash-target holder configured to be soaked in a wash tank and to hold at least one wash-target, the wash-target holder comprising: a tray formed by a plate member, the plate member having a wash-target placing face where a face of the at least one wash-target is placed, and the at least one wash-target having side faces defined at a periphery of the face of the at least one wash-target; a surrounding member being provided on the wash-target placing face of the plate member to surround each of the at least one wash-target; and a defluxion-restricting member which restricts defluxion of the at least one wash-target from the wash-target placing face of the plate member comprising a mesh, wherein an opening is configured to let in and out a solvent in a horizontal direction with respect to the wash-target placing face to wash the at least one wash-target, the opening being formed in peripheries of at least one of the side faces of the at least one wash-target, such that the at least one of the side faces of the wash-target is exposed to solvent, and the surrounding member being integral with the plate member and having intermittently spaced surfaces which intermittently spaced surfaces are substantially perpendicular to the wash-target placing face of the plate member, wherein a spacing formed by the intermittently spaced surfaces defines the opening which lets the solvent in and out at the peripheries of the at least one side face of the at least one wash-target, and the intermittently spaced surfaces restrict movement of the wash-target in a direction along the wash-target placing face.
