Abstract
Provided is an evaporation source for use in a vacuum evaporation apparatus, the evaporation source restricting a local overheating and planning prolonged lifetime. The evaporation source includes: a boat main body having a containing part for the evaporation material; rising plate parts each rising upward from both ends as seen in one direction of the boat main body; and electrode mounting plate parts each extending outward from the respective upper ends of the rising plate parts. The boat main body is heated by applying electric power across both the electrode mounting plate parts, thereby causing the evaporation material inside the containing part to be evaporated. At this time, the rising plate parts are provided with dividing passages for the applied electric current.
