摘要

PROBLEM TO BE SOLVED: To improve a shape accuracy on a transfer face of a plastic article.

SOLUTION: The plastic article 10 has the transfer face 11 formed by causing a resin in a mold cavity to generate a resin pressure and transfer the surface to be transferred. The plastic article 10 has: a projection 40 on at least one face other than the transfer face 11; a concave incomplete transfer part 22 disposed at the same face on which the projection shape 40 is disposed, formed by an incomplete transfer of a face shape of the cavity of the metal die; and a convex incomplete transfer part 21 having a convex shape disposed at least one face other than the transfer face.
