Abstract

The lateral V-shaped groove (2) and the longitudinal V-shaped groove (3), which cross each other, are formed on a surface of the substrate (1). When the optical element (100) is contacted with and supported by four ridges composed of sides (21, 22) of one V-shaped groove and sides (31, 32) of the other V-shaped groove, the optical element is positioned at the three-dimensional support position which is geometrically determined by the four points at which the four ridges and the surface of the optical element come into contact with each other.
