Abstract
A radial line dial plate includes: a substrate body made of resin on which a radial line mark region is molded by a die mark-molding-face of a molding die; a plurality of fine grooves that extend radially outward in a radial direction from a center of the radial line mark region without intersecting with each other and are formed such that a distance therebetween is 1 μm or less at an outermost peripheral end to give a radial line pattern to the radial line mark region; and a metal thin film that is deposited to at least the radial line mark region of the substrate body.

A radial line dial plate comprising:
- a substrate body made of resin on which a radial line mark region is molded by a die mark-molding-face of a molding die;
- a plurality of fine grooves that extend radially outward in a radial direction from a center of the radial line mark region without intersecting with each other and are formed such that a distance therebetween is 1 μm or less at an outermost peripheral end to give a radial line pattern to the radial line mark region;
- and
- a metal thin film that is deposited to at least the radial line mark region of the substrate body.
A radial line dial plate comprising:
- a substrate body made of resin that is integrally molded by a molding die;
- and
- a metal thin film that is deposited to at least a radial line mark region provided on a surface of the substrate body, wherein
- the radial line mark region extends in a radial direction from a center of the substrate body and is formed into a radial line pattern shape by a large number of groove portions which are random in groove depth, respectively.
