1. A shake correction unit that corrects a shake of an optical module having at least an imaging element, the shake correction unit comprising:
a movable body;
a fixed body that movably supports the movable body; and
a circuit board connected to the movable body,
wherein
the movable body is rotatable about at least a first rotation axis extending in a first direction,
the circuit board includes a first circuit board and a second circuit board,
the first circuit board has
a first end portion connected to the movable body on a first side in a second direction orthogonal to the first direction with respect to the movable body, and
a second end portion that is connected to the fixed body,
the second circuit board has
a first end portion connected to the movable body on the first side in the second direction with respect to the movable body, and
a second end portion that is connected to the fixed body,
the first circuit board has
a first portion extending from a first side in a third direction orthogonal to each of the first direction and the second direction to a second side in the third direction,
a second portion extending from the second side in the third direction to the first side in the third direction, and
a third direction bent portion in which an end portion on the second side in the third direction of the second portion is bent in the third direction with respect to an end portion on the second side in the third direction of the first portion, and
the second circuit board has
a first portion extending from the second side in the third direction to the first side in the third direction,
a second portion extending from the first side in the third direction to the second side in the third direction, and
a third direction bent portion in which an end portion on the first side in the third direction of the second portion is bent in the third direction with respect to an end portion on the first side in the third direction of the first portion.
