A lens barrel includes a lens group that conducts light from a subject, a lens shell that holds the lens group; a string-formed shape memory alloy element that moves the lens shell in a direction of an optical axis, and a pair of guide shafts formed approximately in parallel to the optical axis of the lens group, wherein the lens shell is integrally formed with a cylindrical portion through which one of the guide shafts penetrates, the string-formed shape memory alloy element contacts with a portion of the lens shell at an approximately central portion of the alloy element, and both ends of the alloy element are fixed at respective positions with a line connecting the optical axis of the lens group and a center of the cylindrical portion between the positions.
