A shake correction optical unit with a shake correction function may cause a movable body including an optical module to swing around an X axis and a Y axis that are perpendicular to an optical axis L. A flexible printed board may include a second folded portion drawn from the movable body in a +Y direction, and bent in a direction of the optical axis L and folded once; and a first folded portion bent to extend from the second folded portion in the +Y direction and folded once. At least one of the second folded portion or the first folded portion may be thus easily bendable when the movable body swings in either direction around the X axis or around the Y axis.

A camera module includes a carrier, disposed in an internal space of a housing, configured to receive a lens barrel, and having an external rolling portion corresponding to the internal rolling portion on an exterior side; a focus adjustment driver configured to generate a driving force to move the carrier in an optical-axis direction in the housing; and a rolling member disposed between the internal rolling portion and the external rolling portion. Either one or both of the internal rolling portion and the external rolling portion includes a guide groove, formed on an external surface of a mold forming an exterior of the housing or the carrier, including a pair of rolling sides facing each other with a predetermined angle, and a reinforcing insert made of a material having greater strength than a material of the mold.

An imaging correction unit and an imaging module are provided. The imaging correction unit has an optical axis and includes four wedge optical elements with the same structure. The wedge optical elements are disposed sequentially on the optical axis. Each of the wedge optical elements has a minimum thickness dimension at a first edge and a maximum thickness dimension at a second edge. A connection line between the first edge and the second edge forms a symmetry axis of the each of the wedge optical elements. When a beam transmitted along the optical axis of the imaging correction unit passes sequentially through the wedge optical elements and is imaged at a center of an imaging surface, the symmetry axis of any one of the four wedge optical elements is at an angle of 90 degrees relative to the symmetrical axis of one of adjacent wedge optical elements.

The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction.
