Claim Text:
1. A method of manufacturing an evaporating material comprising the steps of: forming a solidified body of a rare-earth metal or of an alloy thereof by melting the rare-earth metal or the alloy thereof, by dipping a base member made of a fire-resistant metal into a molten bath of the rare-earth metal or of the alloy thereof in a state of maintaining the base member at a temperature below the melting temperature of the rare-earth metal or the alloy thereof, and thereafter by pulling up the base member to thereby form on a surface of the base member the solidified body; detaching the solidified body off from the base member; and working the solidified body thus detached into a plate shape.
