摘要： The present invention aims at providing a prepreg for producing a laminate suitable as a structural material, and a laminate, which have excellent tensile shear joining strength, fatigue joining strength, and interlaminar fractural toughness values, and can be firmly integrated with another structural member by welding. The present invention is a prepreg including the following structural components [A], [B], and [C], wherein [C] is present on a surface of the prepreg, [C] is a crystalline thermoplastic resin having a glass transition temperature of 100° C. or higher or an amorphous thermoplastic resin having a glass transition temperature of 180° C. or higher, and the reinforcing fibers [A] are present which are included in a resin area including [B] and a resin area including [C] across an interface between the two resin areas: [A] reinforcing fibers; [B] a thermosetting resin; and [C] a thermoplastic resin.
