PROBLEM TO BE SOLVED: To provide an adherent composition for a polyaryletherketone resin material, which provides higher adhesiveness to the polyaryletherketone resin material than before.SOLUTION: Provided is an adherent composition for a polyaryletherketone resin material, which contains a polymerizable monomer having a benzoyl skeleton in a molecule. The polymerizable monomer having a benzoyl skeleton is preferably one having a hydrogen-bonding functional group. Further, the composition preferably contains a polymerizable monomer having no benzoyl skeleton. The adherent composition for a polyaryletherketone resin material of the present invention is useful as a primer and an adhesive, or in a dental material field.SELECTED DRAWING: None
