To provide a shutter driving device and a camera having stable running characteristics of light-shielding blades and improved accuracy of exposure time.

A concave spherical surface part 1411 is provided on an attraction part attachment part 141k so that a convex spherical surface part 1415 can be attached to a magnet attraction part 141e. A convex spherical surface 1415a of the convex spherical surface part 1415 is then slidably fitted to a concave spherical surface 1411a of the concave spherical surface part 1411.
