Evaporation source for vacuum evaporation apparatus

An evaporation source for use in a vacuum evaporation apparatus which is to evaporate an evaporation material onto a substrate by evaporating the evaporation material in a vacuum chamber, the evaporation source comprising:

• an evaporation boat 3 including a boat main body having a containing part for the evaporation material, and electrode mounting plate parts respectively extending outward at both ends of the boat main body;
• material feeding means for feeding a wire-shaped evaporation material, from an upper side of the containing part, thereinto such that, by charging electric current across both electrode mounting plate parts, the boat main body is heated to evaporate the evaporation material inside the containing part;
• wherein the evaporation source further comprises:
• a supporting means coming into contact, from below, with a bottom plate part of the boat main body that defines the containing part, the containing part being under an action of weight to be caused by the feeding of the evaporation material;
• and
• wherein the supporting means has a supporting plate disposed in a state in which an upper end of the supporting plate is in contact with the bottom plate part of the boat main body, a free-end side of the supporting plate being an edge of the supporting plate and contacting only a portion of the bottom plate part, the supporting plate extending from the free-end side away from the bottom plate part.
