The present invention provides a metallic coating having a sheen and
having a discontinuous structure at high productivity and low cost by
using sputtering. A resin product includes a resin base material, and a
metallic coating having a sheen and a discontinuous structure that is
deposited on the resin base material so as to include a portion in which
a high-formation metal that relatively readily forms a discontinuous
structure when using vacuum vapor deposition is sputtered, and
thereafter, a low-formation metal that does not relatively readily form a
discontinuous structure when using vacuum vapor deposition is sputtered.
The high-formation metal and the low-formation metal are selected from at
least two species of metals whose crystal structures are identical and
whose lattice constant difference is within 10%.
