PROBLEM TO BE SOLVED: To provide a vapor deposition mask and a vapor deposition mask with a frame, which satisfies high definition with light weight, having strength of an opening, and which prevents shadow generation, even when the mask is made large.SOLUTION: Metal masks 10 in which a slit 15 is provided on one face of a resin mask 20 with an opening 25 corresponding to a deposited pattern are stacked, in a deposition mask 100. In an inner wall face composing the opening 25 has at least one inflection point in a cross section of a thickness direction. A first intersection Q1 is an intersection of the inner wall face with a first face which is a face not contacting the metal mask 10 of the resin mask 20. A second intersection Q2 is an intersection of the inner wall with a second face which is a face contacting the metal mask 10 of the resin mask 20. In inflection points, S1 is a first inflection point from the first intersection Q1 to the second intersection Q2. An angle of a straight line connecting the first intersection Q1 and the first inflection point S1, to the first face, is made larger than an angle of a straight line connecting the first inflection point S1 and the second inflection point Q2, to the second face, in the deposition mask 100. |
