To provide a press tool for improving designability of a plurality of convex shapes and molding the same, a press die, a press device, a press work method, and a press molded product.SOLUTION: A press tool (Pt) comprises: a die (18) including a recess group (40) with a plurality of recesses in which prescribed convex shapes are inverted; and a punch (16) including a protrusion group (39) having a plurality of protrusions of the prescribed convex shape, and beads (15, 29) arranged at least either above or below the protrusion group. A metal thin plate (1) is molded into a plurality of convex shapes on a slant face (2a) while being compressed by the recess group and the protrusion group while molding the slant face (2a) on the planar work-piece (1) pinched between the die (18) and the punch (16) by bending or drawing by the punch (16).SELECTED DRAWING: Figure 5 【課題】複数の凸形状の意匠性を向上して成形するプレス工具、プレス金型、プレス装置、プレス加工方法、及び、プレス成形品を提供する。【解決手段】所定の凸形状を反転させた複数の凹部を有する凹部群（４０）を備えるダイ（１８）と、所定の凸形状の複数の凸部を有する凸部群（３９）と、凸部群の上方及び下方の少なくとも一方に配置されたビード（１５、２９）と、を備えるパンチ（１６）と、を備えた、プレス工具（Ｐｔ）である。パンチ（１６）の曲げまたは絞り加工により、ダイ（１８）とパンチ（１６）とに挟まれた平面状の被加工物（１）に斜面（２ａ）を成形しつつ、金属薄板（１）を凹部群及び凸部群で圧縮しながら斜面（２ａ）に複数の凸形状を成形する。【選択図】図５
