A sheet metal workpiece storage device for storing one or more plate-like workpieces made of sheet metal, comprising: a first plate-like member on a bottom surface side disposed in a horizontal direction; a second plate-like member disposed in a vertical direction that is perpendicular to the horizontal direction; a first position restricting mechanism which is provided integrally with the first plate-like member or separately from the first plate-like member on the first plate-like member, wherein the first position restricting mechanism is configured to engage a first end portion of the workpiece that comprises a first side of the workpiece in a state in which the workpiece is oriented in the vertical direction and both a front surface and a rear surface of the workpiece are oriented in a plane that extends in the vertical direction such that the first side of the workpiece opposes the first plate-like member, thereby restricting a position of the first end portion in a plate thickness direction of the workpiece, the plate thickness direction of the workpiece being oriented perpendicular to the front surface and the rear surface of the workpiece; and a second position restricting mechanism which is provided integrally with the second plate-like member or separately from the second plate-like member on the second plate-like member, wherein the second position restricting mechanism is configured to engage a second end portion of the workpiece that comprises a second side of the workpiece in the state in which the workpiece is oriented in the vertical direction such that the second side of the workpiece opposes the second plate-like member, thereby restricting a position of the second end portion in the plate thickness direction of the workpiece, wherein the first position restricting mechanism comprises a plurality of comb teeth members disposed in a first direction along the first side of the workpiece with a space provided between adjacent comb teeth members, said comb teeth members comprising a plurality of first slits arranged in a second direction orthogonal to the first direction such that the workpiece storage device is configured to store a plurality of workpieces with the first end portions being inserted into corresponding first slits, and each of the plurality of comb teeth members is made of metal, and is formed by bending a metal plate into a mountain shape and by forming the plurality of first slits, wherein the second position restricting mechanism is formed with a plurality of second slits arranged in a direction orthogonal to the second side into which the second end portion is configured to be inserted, and the second slits are formed at a position that corresponds to the first slits such that the first slits and the second slits are positioned on a straight line. a first plate-like member on a bottom surface side disposed in a horizontal direction;
