摘要： An electrical steel sheet with an insulation coating excellent in punchability, coating adhesion property and coating film property after annealing, even without containing any chromium compound in the insulation coating. The insulation coating is formed by applying a surface-treatment agent to at least one side of the electrical steel sheet and drying the surface-treatment agent. The surface-treatment agent contains trialkoxysilane and/or dialkoxysilane (A) in which a substituent bound to Si is constituted only by at least one non-reactive substituent selected from the group consisting of hydrogen, an alkyl group, and a phenyl group; and a silane coupling agent (B), at a mass ratio (A/B) of 0.05 to 1.0.
