PROBLEM TO BE SOLVED: To effectively mount a flexible printed board while effectively suppress floating of the flexible printed board. SOLUTION: The lens barrel comprises a fixed cylinder, a movable cylinder provided to be movable in an optical axis direction relative to the fixed cylinder, a drive unit body held by the fixed cylinder, and a flexible printed board which is stuck the inner circumferential surface of the movable cylinder at one end side, with a mounting surface formed through a bent part at the one end being stuck to the inner circumferential surface of the fixed cylinder. A projection to be engaged with a hole formed in the mounting surface of the flexible printed board is formed on the inner circumferential surface of the fixed cylinder, the drive unit body includes an arm part formed to be located on the surface side opposite to the surface with the mounting surface of the flexible printed board stuck thereto, and the height dimension of the projection is set longer than the distance from the surface with the mounting surface of the flexible printed board stuck thereto to the surface of the arm part on the surface side opposite to the surface with the mounting surface stuck thereto.
