Abstract: In an optical unit with a shake correction function, a first inner-side wall surface disposed on an inner side of a first band-shaped portion of a circuit board in a Y-direction and a second inner-side wall surface disposed on an inner side of a second band-shaped portion of the circuit board in an X-direction are defined in an intermediate-member holder, and a first outer-side wall surface disposed on an outer side of the first band-shaped portion in the Y-direction and a second outer-side wall surface disposed on an outer side of the second band-shaped portion in the X-direction are defined on an outer-peripheral side covering portion. An interval between the first inner-side wall surface and the first outer-side wall surface is smaller than an interval between the second inner-side wall surface and the second outer-side wall surface.

Abstract: An optical unit with a runout correction function includes a reflection member, a camera module having a lens and an image pickup element, a holding member that rotatably holds the reflection member and also holds the camera module, and a fixing member that rotatably holds the holding member. A second rotation mechanism rotates the reflection member held in the holding member with an optical axis direction, which is a direction of an optical axis of the lens, as an axis direction of the rotation and is capable of runout correction in a yaw direction. In the optical unit with a runout correction function, when the runout correction in the yaw direction is performed, the image pickup element held in the holding member is rotated together with the reflection member with the optical axis direction as the axis direction of rotation.

Abstract: An optical unit with a shake correction function may include a swing body which holds an optical element; a swing support mechanism structured to swingably support the swing body between a reference posture, where an axial line previously set and an optical axis are coincided with each other, and a tilted posture, where the optical axis is tilted with respect to the axial line; and a support body which supports the swing body through the swing support mechanism; and a weight which is used so that a swing center of the swing body and a gravity center of the swing body are coincided with each other in a direction of the axial line. The swing body may include a fixed region to which the weight is fixed. A fixed position of the weight may be changeable in the fixed region in a direction of the optical axis.
