PROBLEM TO BE SOLVED: To resolve the problem that a relative distance between a correction lens and a hole element in a sliding direction of a main guide shaft is changed to degrade the position detection precision of the correction lens in a conventional image blur correction device. SOLUTION: An image blur correction device is provided with a correction lens, a first moving frame, a first main guide shaft, a first auxiliary guide shaft, a first driving means, a second moving frame movably supporting the first moving frame, a second main guide shaft, a second auxiliary guide shaft, a second driving means, and a fixed base movably supporting the second moving frame. A first hole element 26 for detecting relative positions of the first moving frame and the fixed base 23 in a first direction X and a second hole element 27 for detecting relative positions of the second moving frame and the fixed base 23 in a second direction Y are provided, and a distance from the first main guide shaft 33 to the correction lens 15 in the second direction Y and a distance from the first main guide shaft 33 to the first hole element 26 in the second direction are approximately equalized, and a distance from the second main guide shaft 47 to the correction lens 15 in the first direction X and a distance from the second main guide shaft 47 to the second hole element 27 in the first direction are approximately equalized.
