An optical scanning element includes: a first member which is constituted of a mirror portion, a mirror supporting portion and a frame portion; a second member which fixes and holds the frame portion of the first member thereon; and a piezoelectric body. The frame portion includes a beam portion and fixing portions which are positioned at both ends of the beam portion, the mirror supporting portion is connected to the beam portion at a connection point, and the piezoelectric body is fixedly mounted on the frame portion in a state that the piezoelectric body extends toward the connection point of the beam portion from the fixing portion to a position not over the connection point thus extending over the beam portion and the fixing portion. Due to such constitution, a swinging angle of the mirror portion can be increased thus enlarging a scanning angle.
