There are a first step of preparing a transparent concave-convex plate material 16, one side of which having grooves 18 of square cross-section formed by parallel embankments 17, a second step of covering top surfaces 19 of the embankments 17 and bottom surfaces 20 of the grooves 18 with pieces of resin peelable by ultraviolet irradiation 22, 23, a third step of vapor-depositing a metal on the obverse surface of the concave-convex plate material 16 having the top surfaces 19 of the embankments 17 and the bottom surfaces 20 of the grooves 18 covered with the pieces of the resin peelable by ultraviolet irradiation 22, 23, and a fourth step of removing, by irradiating ultraviolet light from the reverse surface of the concave-convex plate material 16, the pieces of the resin peelable by ultraviolet irradiation 22, 23 having the surfaces thereof vapor-deposited by the metal. |
