Document Type and Number:
Japanese Patent JP2006003382
Kind Code:
A
Abstract:
To provide an optical unit which has a simple constitution and can prevent optical axis slippage between optical members due to the change in the thickness of adhesive.
In the optical unit constituted of a plurality of optical members, including at least a 1st optical member 1001 and a 2nd optical member 1002 adhered to the 1st optical member, the 2nd optical member has a 1st face 1002d being almost in parallel with respect to an adhesion face 1002c with the 1st optical element.
