PROBLEM TO BE SOLVED: To provide an image fluctuation correcting apparatus configured to achieve simple and small structure. SOLUTION: The image fluctuation correcting apparatus rotates, in an arcuate form, a first rotary apex angle prism 35 held in a first prism holding member 41 around a first shaft 42, which is substantially parallel to an optical axis K within a frame body 31, in a direction for canceling an amount of horizontal fluctuation by electromagnetic force generated between a first drive coil 46 and a first magnet 44 by causing electric current to flow in the first drive coil in a direction for canceling the amount of horizontal fluctuation of a picked up image. Also, the image fluctuation correcting apparatus rotates, in an arcuate form, a second rotary apex angle prism 36 held in a second prism holding member 51 around a second shaft 52, which is located 180-degree angle away from the first shaft 42, in a direction for canceling an amount of vertical fluctuation by electromagnetic force generated between a second drive coil 56 and a second magnet 54 by causing electric current to flow in the second drive coil in the direction for canceling the amount of vertical fluctuation of a picked up image.
