Claim Text:
1. A manufacturing method for an organic EL element including a coating film having a predetermined pattern on a substrate, the method comprising: a vapor deposition step of forming the coating film by causing vapor deposition particles to adhere to the substrate, wherein the vapor deposition step is a step in which with the use of a vapor deposition unit including a vapor deposition source having a vapor deposition source opening that discharges the vapor deposition particles and a vapor deposition mask disposed between the vapor deposition source opening and the substrate, in a state in which the substrate and the vapor deposition mask are spaced apart at a fixed interval, the vapor deposition particles that have passed through a plurality of mask openings formed in the vapor deposition mask are caused to adhere to the substrate while one of the substrate and the vapor deposition unit is moved relative to the other, when a relative movement direction between the substrate and the vapor deposition unit is defined as a first direction and a direction orthogonal to the first direction is defined as a second direction, the vapor deposition unit includes, between the vapor deposition source opening and the vapor deposition mask, a plurality of limiting plates whose positions in the second direction are different, each of the plurality of limiting plates limits an incidence angle of the vapor deposition particles entering the respective mask openings, as viewed in the first direction, the vapor deposition unit further includes a second limiting plate between the vapor deposition source openings and the vapor deposition mask, the second limiting plate prevents vapor deposition particles discharged from the vapor deposition source openings on one side of the second limiting plate in the first direction from entering the mask openings disposed on the other side in the first direction, and wherein the second limiting plate is bent in a zigzag pattern.
