An image blur compensation apparatus includes first and second driving units ( 17 a, 17 b, 16 a, 16 b) having functionally equivalent members each other. A resultant force which acts on a holding unit ( 12 ) when in-phase driving signals of the same amount are applied to the first and second driving units differs in magnitude from a resultant force which acts on the holding unit when reverse-phase driving signals of the same amount are applied to the first and second driving units. The first and second driving units are arranged such that these resultant forces become perpendicular to each other.
