An image blur correction apparatus according to the present invention includes a base, a movable holding member, a support mechanism that supports the movable holding member to be movable within a plane vertical to an optical axis of a lens, a driving means for driving the movable holding member, a position detecting means, and a returning means for returning the movable holding member to a pause position, wherein the driving means includes coils (121, 131) fixed to the base and drive magnets (122, 132) fixed to the movable holding member, the returning means includes return magnets (161, 162) fixed to the base to face the drive magnets, the position detecting means includes magnetic sensors (171, 172) fixed to the base, and the support mechanism includes at least three concave portions (104) provided on the base, at least three spheres (150) rollably arranged in the concave portions, and at least three abutment surfaces (114) provided on the movable holding member to abut on the spheres. With this arrangement, the lens can be automatically centered while achieving simplification of the structure and miniaturization.
