Module driving device

A module driving device, comprising:

• a module holder configured to hold an optical module including a lens body and an imaging element;
• a connection member connected to the module holder such that the module holder is rockable about a first axial line that crosses a direction of an optical axis;
• a fixed-side member connected to the connection member such that the connection member is rockable about a second axial line that crosses the direction of the optical axis and is perpendicular to an axial line direction of the first axial line;
• and
• a driver including a plurality of shape memory alloy wires configured to move the module holder relative to the fixed-side member, wherein
• two first supports are fixed to a first member and disposed so as to face each other across the optical axis, in the axial line direction of the first axial line, the first member being one of the module holder or the connection member,
• at least a surface of the two first supports that faces a second member is formed as a projecting curved surface, the second member being another of the module holder or the connection member,
• the two first supports are formed of a metal or ceramic, and
• the module holder and the connection member are disposed to overlap with each other in the direction of the optical axis via the two first supports.
