Abstract
Provided is a photographing optical device, which is able to reliably correct an unintentional movement by hand of a user by improving the constitution of a camera unit driving mechanism for correcting the deflection of a camera unit. In order that a camera unit is made to be rocked to correct the unintentional movement, a photographing optical device includes a first camera unit drive mechanism and a second camera unit drive mechanism, which are so disposed at two side portions sandwiching a pivot portion therebetween as to make a pair. In these camera unit drive mechanisms, camera unit driving magnets are held on the side of the camera unit as a movable body side, and camera unit driving coils are held on the side of a stationary body. The camera unit is pushed toward the pivot portion by a gimbal spring.
