PROBLEM TO BE SOLVED: To provide a resin form plate for a concrete form which is excellent in releasability and hardens the surface of hardened concrete. SOLUTION: The resin form plate is used by bonding it to the surface of a concrete form. On the surface of the form plate, active-hydrogen-containing amino groups are present as functional groups. When measured by an X-ray photoelectron spectrometry (XPS), the ratio of the number of nitrogen atoms derived from the surface amino groups to the number of carbon atoms is 0.1 atom.% or higher but not higher than 20 atom.%.
