PROBLEM TO BE SOLVED: To provide a method for producing a pressure sensitive adhesive sheet containing an ultraviolet-curable acrylic adhesive layer which shows high conversion per unit luminous energy, provides excellent productivity, and a good balance of adhesive performance such as holding power at high temperature and the like.SOLUTION: Provided is a method for producing an adhesive sheet, comprising the steps of coating an ultraviolet-curable acrylic adhesive composition containing at least a monomer component containing an alkyl (meth)acrylate and a photoinitiator on a substrate, and forming an adhesive layer by curing the ultraviolet-curable acrylic adhesive composition by irradiating ultraviolet light. In the step of forming an adhesive layer, an ultraviolet lamp which irradiates ultraviolet light is an LED lamp, the ultraviolet light is irradiated intermittently, time of a light period where the ultraviolet light is irradiated is 1 to 30 seconds, time of a dark period when the ultraviolet light is not irradiated is 0.1 to 20 times the time of the light period. |
