Abstract

An object of the present invention is to provide a radical- polymerizable adhesive composition for laminating and bonding steel plates, capable of obtaining an adhesive laminate that contributes to simplification of a process in an adhesive lamination method, and high performance and high reliability of a rotor or a stator of a motor. A radical-polymerizable adhesive composition for laminating and bonding steel plates, exhibiting a value of 8.0 MPa or more in a tensile shear adhesive strength test to an electromagnetic steel plate, and containing: component (A): a radical-polymerizable compound; component (B): a radical-polymerization initiator; and component (C): a phosphate compound having a group represented by the following general formula (1) or (2).
