Abstract

A vehicular decorative member is curved as a forward-bulging shape, and includes a transparent base, a transferred layer, a metallic layer, and a base layer. The transparent base includes a front face, and a rear face. The transparent base'"'"'s rear face has an ordinary section, and a recessed section. The transferred layer, the metallic layer, and the base layer are disposed on the transparent base'"'"'s rear-face side in this order. The vehicular decorative member further includes a transfer sheet turning into the transferred layer. The transfer sheet includes a support film, and an adhesive layer, a decorative layer and a release layer that are formed on the support film in this order. The transfer sheet makes the transferred layer when the support film is removed from the release layer after pressing the transfer sheet onto the transparent base'"'"'s ordinary section while heating the transfer sheet.

Claims

1. A decorative member for vehicle, comprising:

a transparent base made from a resinous material and including a front face and a rear face, the rear face having an ordinary section and a recessed section dented more forward than is the ordinary section;

a transferred layer;

a metallic layer;
