Optical assembly with shake correction function

An optical assembly with a shake correction function to correct a shake of an optical module, the optical assembly comprising:

• a movable body that includes the optical module;
• a frame body radially outward of the movable body in a radial direction with respect to an optical axis of the optical module;
• and
• a plurality of support portions that swingably support the movable body with respect to the frame body;
• wherein
• each of the plurality of support portions includes a guide portion and a preload portion;
• the guide portion is between the movable body and the frame body to support the movable body;
• a radially inner end portion of the preload portion is connected to a radially outer end portion of the guide portion;
• a radially outer end portion of the preload portion is supported by the frame body;
• one of the movable body and the guide portion includes a first convex surface protruding from the one of the movable body and the guide portion toward another of the movable body and the guide portion;
• the another of the movable body and the guide portion includes a first concave surface in contact with the first convex surface;
• the first convex surface and the first concave surface have a spherical shape;
• and
• the preload portion pushes the guide portion toward the movable body.
