A lens barrel is provided with which manufacturing costs can be reduced. The lens barrel (3) has a first lens group (G1), a second lens group (G2), a third lens group (G3), a first support frame (10) that supports the first lens group (G1), a second support frame (20) that supports the second lens group (G2), a third support frame (30) that supports the third lens group (G3), a first driving unit (50), a second driving unit (60), and a shutter unit (29) that is fixed to the second support frame (20). The first lens group (G1) has an overall negative refractive power, and includes a prism (PR). The second support frame (20) is driven along a second optical axis (A2) by the first driving unit (50). The third support frame (30) is driven along the second optical axis (A2) by the second driving unit (60).
