PROBLEM TO BE SOLVED: To provide a dial device where a plurality of contact pieces come into contact with an electrode pattern with stable pressure and at high positional accuracy and by which smooth and excellent click feeling is obtained. SOLUTION: The dial device has a base plate 7 where a plurality of electrode patterns 7a to 7c are formed in a concentric circular-arc state, a dial member 1 realizing rotating operation with an axis at the center of curvature of the electrode pattern with respect to the base plate, and a rotating plate capable of rotating integrally with the dial member and equipped with a plurality of contact pieces 5e, 5f and 5g coming into contact with a plurality of electrode patterns and click parts 5a to 5d forming a part of a click mechanism making a click in the rotation of the dial member. As for the plurality of contact pieces, at least their parts on a base end side are formed to have arc shape, the radii of curvature of the arc-shaped parts of the contact pieces are the same as each other substantially, and the positions of the centers of curvature thereof are different.
