PROBLEM TO BE SOLVED: To provide a photocurable adhesive having sufficient heat resistance without through an aging process and a method for producing the same, and to provide a photocurable adhesive precursor composition which can provide such photocurable adhesive.;SOLUTION: A photocurable adhesive having sufficient heat resistance can be provided by irradiating a photocurable adhesive precursor composition containing an ethylenic unsaturated monomer, a prepolymer having a monomer unit derived from a hydrogen donating monomer, and a hydrogen withdrawing type photoinitiator with active rays such as ultraviolet rays, causing a radical polymerization reaction by the monomer unit derived from the hydrogen donating monomer and a polymerizable comonomer existing as a monomer in the prepolymer to form a random branched (co) polymer having a branched structure, without through an aging process.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
