Zusammenfassung:	To suppress vacuum leakage between a sheet and a mold during vacuum forming.SOLUTION: A mold 51 is used for vacuum-forming a sheet 11 and has a facing surface 51a that faces the sheet 11 during vacuum forming, the mold including: a suction hole 511, provided in a first region 51b of the facing surface 51a, for vacuum-forming the sheet 11 through vacuum suction; a linear groove 512 provided in a second region 51c surrounding the first region 51b on the facing surface 51a; and an adsorption hole 513 that has an opening 513a provided at least partially in a wall surface 512a of the linear groove 512 and holds the sheet 11 in the mold 51 through vacuum adsorption.SELECTED DRAWING: Figure 7 【課題】真空成形時にシートと金型との間の真空漏れを抑制する。【解決手段】金型５１は、シート１１の真空成形に用いられ、真空成形時にシート１１と対向する対向面５１ａを有する金型５１であって、対向面５１ａの第１領域５１ｂに設けられ、シート１１を真空吸引して真空成形する吸引孔５１１と、対向面５１ａの第１領域５１ｂを囲う第２領域５１ｃに設けられた線状溝５１２と、少なくとも一部が線状溝５１２の壁面５１２ａに設けられた開口５１３ａを有し、真空吸着によって金型５１にシート１１を保持させる吸着孔５１３と、を備える。【選択図】図７
