Abstract
A synthetic resin globe for a light-emitting device is produced by molding an intermediate product with an injection molding die, softening the intermediate product in a heating apparatus, expanding it with compressed air in a die to form a globe shape, transferring a concavo-convex shape formed in a core of the injection molding die to form a concavo-convex shape on an inner wall of the intermediate product, so that the concavo-convex shape can be easily formed into a desired shape in a lower part of an inner wall of the globe.
