The present invention provides a method for manufacturing an adhesive sheet having an ultraviolet-curable acrylic adhesive agent layer having high polymerization degree per unit dosage, good productivity and good balance of adhesive performance such as retentiveness at a high temperature. The method of manufacturing the adhesive sheet includes a coating process of an ultraviolet-curable acrylic adhesive composition including a monomer component containing (meth)acrylic acid alkyl ester and a photopolymerization initiator, and a forming process of an adhesive layer by curing the ultraviolet-curable acrylic adhesive composition. During the manufacturing of the adhesive layer, an ultraviolet lamp for radiating ultraviolet is an LED lamp, and ultraviolet is radiated intermittently. Light period of irradiating the ultraviolet is 1 to 30 seconds, and dark period of not irradiating the ultraviolet is 0.1 to 20 times the light period. |
