Zusammenfassung:PROBLEM TO BE SOLVED: To provide an optical instrument capable of being reduced in size in a radial direction.SOLUTION: The optical instrument comprises: a correction optical system for correcting a blur of an optical image; a magnet and a coil for moving the correction optical system to a direction orthogonal to an optical axis of the correction optical system; a movable member capable of holding one of the magnet and the coil and the correction optical system, and moving to a direction orthogonal to the optical axis; a stationary member holding the other of the magnet and the coil and stationary to a direction orthogonal to the optical axis; and a flexible printed circuit board including a straight line part extending in an optical axis direction of the correction optical system. The other and the straight line part overlap each other when viewed in an optical axis direction of the correction optical system.SELECTED DRAWING: Figure 8 【課題】 本発明は従来よりも径方向への小型化が可能な光学機器を提供することを目的とする。【解決手段】 光学像のぶれを補正するための補正光学系と、前記補正光学系を前記補正光学系の光軸と直交する方向へ移動させるためのマグネット及びコイルと、前記マグネット及びコイルの一方及び前記補正光学系を保持するとともに前記光軸と直交する方向に移動可能な可動部材と、前記マグネット及びコイルの他方を保持するとともに前記光軸と直交する方向には不動の固定部材と、前記補正光学系の光軸方向に伸びる直線部を有するフレキシブルプリント基板と、を備え、前記補正光学系の光軸方向視において、前記他方と前記直線部が重なっている、ことを特徴とする光学機器。【選択図】 図8
