A blur correction mechanism includes: a first guide shaft extending in a first direction, the direction being a predetermined direction orthogonal to the optical axis of the lens groups; a base frame supporting the first guide shaft; a first correcting moving frame supported by the base frame so as to be movable in the first direction via the first guide shaft; a second guide shaft extending in a second direction orthogonal to both the optical axis and the first direction, and being supported by the first correcting moving frame; and a second correcting moving frame supported by the first correcting moving frame so as to be movable in the second direction via the second guide shaft, and holding the lens groups therein. The first guide shaft and the second guide shaft are positioned so as to be substantially coplanar in a plane orthogonal to the optical axis.
