Patent ID: 8913097

Claim:
An optical scanning device comprising: an optical element; and an optical base, wherein the optical element includes a first bonding surface, while the optical base includes a second bonding surface, a groove in which a bonding agent flows is formed in at least one of the first bonding surface of the optical element and the second bonding surface of the optical base, the optical element is bonded and fixed to the optical base through the first bonding surface and the second boding surface by the bonding agent, and the groove has a T-shape when viewed in cross section, the T-shape including a first portion linearly extending in a depth direction from the at least one of the first bonding surface and the second bonding surface, and a second portion linearly extending perpendicularly to the first portion and intersecting the first portion at a region separate from the at least one of the first bonding surface and the second bonding surface.
