A micro movable device includes a base substrate, a fixed portion bonded to the base substrate, a movable portion having a fixed end connected to the fixed portion and extending along the base substrate, and a piezoelectric drive provided on the movable portion and the fixed portion on a side opposite to the base substrate. The piezoelectric drive has a laminate structure provided by a first electrode film contacting the movable portion and the fixed portion, a second electrode film and a piezoelectric film between the first and the second electrode films. At least one of the movable portion and the fixed portion is provided with a groove extending along the piezoelectric drive.
