Blur correction apparatus for correcting blurring of an image photographed using a photographic optical system comprises a blur correction optical system acting to correct image blurring during photographing, a blur correction drive section for electromagnetically driving the blur correction optical system, and a lock member for locking the blur correction optical system. The blur correction drive section has a permanent magnet, one surface of which is used in the blur correction drive section, and another surface of which is used in a lock member drive section. The blur correction drive section is fixed to the permanent magnet and includes a yoke having projections formed at prescribed intervals along the permanent magnet and four coils opposing to both the permanent magnet and the projections with a prescribed gap and connecting to the blur correction optical system.
