description A plastic article is formable by using a metal die having a cavity to accommodate melted resin therein at a given pressure. The plastic article includes a transfer face to which is transferred a face shape of the metal die, a projection disposed at least one face other than the transfer face, an incomplete transfer face having a concave shape disposed at the same face on which the projection is disposed, formed by an incomplete transfer of a face shape of the cavity of the metal die, and an incomplete transfer face having a convex shape disposed at least one face other than the transfer face.
