摘要:
A lens driving apparatus 1 of the present invention includes a substantially cylindrical yoke 3; a base 5 to which the yoke 3 is attached; a carrier 7 having a lens; a coil 10; and a magnet 13, wherein the carrier 7 is moved in a direction of an optical axis of a lens by electromagnetic force generated by passing current through the coil 10, the base 5 is substantially square-shaped seeing from a plane, the yoke 3 is placed at an inner position of the base 5, the yoke 3 has an outer peripheral wall 3a and an annular inner peripheral wall 3b to be spaced to each other, each magnet is placed between the outer peripheral wall and the inner peripheral wall and at a position corresponding to a base corner portion of the base 5, a space between the outer peripheral wall 3a and the inner peripheral wall 3b positioned at a base side portion 3e is made narrower than a space between the outer peripheral wall 3a and the inner peripheral wall 3b positioned at the base corner portion.
