摘要： An image blur correction apparatus includes a correction lens, a first guide section, a second guide section, a first driving section, a second driving section, and a position detection section. In the image blur correction apparatus, the first and second driving section has first and second coils, a magnet to apply magnetic force to the first and second coils, and a yoke to support the magnet. The two coils are disposed in an intersecting and overlapping relationship with each other such that the direction of propelling force generated by the first coil and the direction of propelling force generated by the second coil are directed to the first direction and the second direction, respectively. The position detection section detects the magnetic force of the magnet to detect the position of the correction lens.
