A mobile terminal, comprising: a terminal body; and a camera module located at one side of the terminal body, wherein the camera module includes: a first lens assembly; a second lens assembly located below the first lens assembly along a same optical axis; a diaphragm located between the first lens assembly and the second lens assembly, and being shaped to have an aperture; and an actuator configured to provide reciprocal movement of the first lens assembly relative to the second lens assembly, characterized in that the diaphragm includes: a first blade having a first through hole; a second blade having a first through hole and being configured to change the aperture of the diaphragm according to relative motion with respect to the first blade; a link member coupled to respective end parts of the first blade and the second blade, and configured to move the first blade and the second blade according to rotation of the link member; and a motor coupled to one side of the link member and being configured to cause the rotation of the link member, wherein the actuator (240, 250) includes: a bobbin shaped to define a region within which the first lens assembly is located; a housing (242, 252) formed to enclose side surfaces of the bobbin; one or more magnetic members provided between the bobbin and the housing; a coil (244, 253) located proximate to the one or more magnetic members, and being configured to generate an electromagnetic force between the coil (244, 253) and the one or more magnetic members; an upper spring formed on an upper surface of the housing (242, 252) and having a corner part formed at a bent part and an edge part formed along an edge of the bobbin; a lower spring formed on a lower surface of the housing (242, 252); and a supporting member configured to connect the upper spring with the lower spring, wherein the supporting member is positioned at a plurality of regions of the upper and lower springs (245, 246), and is formed using one or more wires. a terminal body;
