PROBLEM TO BE SOLVED: To provide a photocurable composition for adhesion excellent in coating suitability and a cured article excellent in adhesiveness and followability to dimensional change, warpage or the like of a member under high temperature and high humidity.SOLUTION: There is provided a photocurable composition for adhesion containing a radical initiator (A) containing a radical initiator generating radical by active ray (A1) and a polymerizable material (D) containing (meth)acrylate (D1) having a polymer skeleton having average functional group number of a (meth)acryloyl group of 1 or more and less than 2, where the content of the radical initiator generating radical by active ray (A1) is 70 to 100 wt.% based on the weight of the radical initiator (A) and thixotropy index at 38°C defined by following formula (1) of the (meth)acrylate (D1) is 0.8 to 1.4. Thixotropy index=(viscosity at shear rate of 0.01/s)/(viscosity at shear rate of 10/s) (1).SELECTED DRAWING: None |
