摘要： A manufacturing method of a lens barrel is disclosed. According to one implementation, the manufacturing method includes the following steps. A first lens holding section protrusion step inserts a first lens holding section from one end of a barrel frame to a hollow section to protrude from the other end. A second lens holding section suction step sucks a convex surface section. A first lens holding section contact step brings the planar surface section into contact with the first lens holding section. A lens holding switching step releases suction of the convex surface section, and the planar surface section is held by the first lens holding section. A barrel frame contact step moves the first lens holding section or the lens barrel so that a surrounding edge section is brought into contact with a lens receiving section.
