Abstract:
1. An evaporation apparatus comprising: an elongated crucible having an upper opening and storing an evaporation material; an electric heater which covers the upper opening of the elongated crucible, generates heat by causing electric current to flow therein for heating the evaporation material stored in the crucible, and has an opening through which can pass the evaporation material which is vaporized by heating; and a fixing member for pressing and fixing the electric heater onto the elongated crucible, the fixing member including: a curved portion formed by curving a plate-like spring member into a convex shape; side surface portions each bending upward from one of the ends of the curved portion; and claw portions bending toward the inner side to form substantially a right angle at the upper end portions of the side surface portions, wherein, due to spring urging force generated by pressing a vertex of the curved portion onto a bottom of the crucible, inner portions of the respective claw portions contacting the upper edges of the electric heater press the electric heater onto the crucible for fixing the electric heater onto the crucible.
