Abstract To provide a lens which can be positioned in a state where optical performance is hardly lowered even when the lens is shifted because fitting looseness exists between the lens and a lens frame. This lens frame is a lens supporting frame whose surface receiving the lens is formed to be spherical in order to support and hold the lens inside. When the lens frame supports the lens having two spherical surfacesto be opposed, the center of the spherical surface formed on the lens frame is provided at the same place as the center of either spherical surface of the lens, that is, the center.
