A metallic layer is formed on a resin-made dial plate main body by surface treatment. A front surface of the main body is provided with a circular or arc-shaped second design face around a rotation shaft of a pointer, and a first inwardly inclined face and an outwardly inclined face continued to the second design face so as to rim an inside and an outside of the second design face and gradually extending toward a rear surface as extending away from the second design face. These first inwardly inclined face and outwardly inclined face are provided on a smooth face. Other portions except these first inwardly inclined face and outwardly inclined face are provided on a corrugated face on which a plurality of convexes and concaves are formed and having a surface roughness rougher than the smooth face.
