PROBLEM TO BE SOLVED: To provide a continuous fiber-reinforced polyamide molding material superior in mechanical strength, bundling property and releasing property, and moldings excellent in mechanical strength, heat resistance and color tone. SOLUTION: This continuous fiber-reinforced polyamide resin molding material is prepared by impregnating with a polyamide resin a glass fiber bundle to which surface treatment is applied by using a sizing agent comprising a polyurethane resin, a copolymer of an unsaturated monocarboxylic acid or an unsaturated dicarboxylic acid and at least one unsaturated monomer, and a silane coupling agent.
