Claim:
1. A vacuum vapor deposition apparatus comprising: a vaporization container that has a plurality of release holes arranged linearly in an arrangement direction in only one line such that a conductance by the release holes on both end portion sides of the vaporization container is larger than at the center of the vaporization container, wherein the vaporization container is one container containing a vaporization material on one bottom thereof for the plurality of release holes and the vaporization container is configured to be heated so as to evaporate or sublimate the vaporization material such that vapor of the vaporization material is released through the plurality of release holes, and wherein the vaporization material is to be deposited on an entire surface of a substrate by relatively moving the substrate and the vaporization container in a direction perpendicular to the arrangement direction of the plurality of release holes; and a current plate fixed in the vaporization container so as to directly face the vaporization material, the current plate having a plurality of passage holes through which the vapor passes, the passage holes being arranged on both sides of the line of the release holes when viewed from the top of the vaporization container, and as conductance per unit length in the arrangement direction of the plurality of release holes, conductance by the passage holes is made proportional to conductance by the release holes along the arrangement direction, wherein both the conductance by the release holes and the conductance by the passage holes are increasingly larger from the center of the vaporization container to each end portion side of the vaporization container.
