PROBLEM TO BE SOLVED: To provide a resin film key top board with excellent responsiveness to a product shape by making it freely bendable in any or both of X, Y directions or in many steps without applying notches to it. SOLUTION: In this resin film key top board having a plurality of protruded push button sections, part or all of a base section 4 is applied with a plastic deformation process to be freely curved or bent. Individual depression sections 6 are made different in height from the base section 4 as desired. A resin film 2 is drawn to form a plurality of protruded push button sections 3, a fluid resin or a fluid rubber material is filled in the protruded push button sections 3, then the plastic deformation process is applied to part or all of the base section 4 after the fluid resin or fluid rubber material is hardened or solidified. The plastic deformation process may be applied before drawing. The plastic deformation process is applied by patting or pressing with a frog-like jig 26 or by laser beam radiation.
