摘要:
A lens holder holds a plurality of lenses aligned in a direction of an optical axis. This lens holder is at least partially assembled from subunits divided on a plane that includes the optical axis. In a connecting shell that connects a first shell and a second shell and holds an optical element for bending an optical path, an optical path of only one subunit is effectively used. The connecting shell includes a first connecting structure for connecting to the first shell and second connecting structures for connecting to the second shell, the second connecting structures being disposed at two symmetrical positions around the first optical axis.
