Abstract

Disclosed is an energy ray-curable epoxy resin composition wherein the problem of slow curing has been solved, while maintaining high fixation accuracy. Specifically disclosed is an energy ray-curable epoxy resin composition which contains an epoxy resin, a silicate compound that has a cationically curable functional group, and a photoacid generator.

Description

technical field [0001] The present invention relates to an energy ray-curable epoxy resin composition, and particularly relates to an energy ray-curable epoxy resin composition which can maintain high fixing accuracy and has excellent fast curing properties and is suitable for fixing optical components. Background technique [0002] In an optical pickup device, a photocurable adhesive is used to fix a photodetector to a case (Patent Documents 1 and 2). This adhesive is required to have high fixing accuracy and good curability (rapid cure). [0003] Fixing accuracy refers to the accuracy that shows that the photodetector does not move from a predetermined position when the photodetector is fixed to the case. If the fixing accuracy is low, the photodetector will move from a predetermined position during manufacture of the optical pickup device or after an endurance test, making it impossible to perform light detection. Therefore, high fixing accuracy is required. [0004] T...
