    摘要: The present invention enables a photocurable coating agent in which electrical insulation is high, and viscosity is low even not using a solvent, in an insulating coating for coils and the like.
    A photocurable coating agent includes component (A) and component (B), and includes component (A-1) in an amount of 50 to 100% by mass with respect to a total of component (A-1) and component (A-2):
    Component (A): a (meth)acrylate consisting of following component (A-1) or following component (A-1) and following component (A-2);
    Component (A-1): a (meth)acrylate having a cyclic structure;
    Component (A-2): a (meth)acrylate having a chain structure and having three or more (meth)acryloyl groups in the molecule; and
    Component (B): a photoinitiator.
