PROBLEM TO BE SOLVED: To provide a lens barrel that excels in assemblage and workability by reducing the number of components. SOLUTION: The lens barrel includes: an optical system holding part (14) holding an optical system; a contact part that is disposed in contact with a cylindrical member (1) provided on the circumference of the optical system holding part (14); a holding frame (10) having an elastic portion (20) disposed between the optical system holding part (14) and the contact part (27); and a pressing means (11) for pressing the optical system holding part (14) of the holding frame (10) in a direction intersecting the optical axis L of the optical system by bringing the contact part into contact with the cylindrical member (1) by virtue of deformation of the elastic part (20).
