The present invention provides a photocurable adhesive sheet that has both step-followability and shape stability, and is excellent in durability after being attached to an adhered member. The photo-curable adhesive sheet of the present invention is characterized by comprising a first adhesive layer, a second adhesive layer, and an intermediate layer interposed between the first adhesive layer and the second adhesive layer, the intermediate layer is composed of A layer formed of a resin composition containing a (meth)acrylic copolymer as a main component resin and having a cross-linked structure, the first adhesive layer or the second adhesive layer or the two layers are made of a photocurable resin composition When the formed photocurable resin layer is applied with a load of 1 N/cm 2 at 40°C to measure the holding force, the drop time is more than 60 minutes, and when a load of 1 N/cm 2 is applied to measure the holding force at 60°C , The drop time is within 60 minutes. |
