Abstract
A convex fitting portion 30 is provided on a center side to protrude from a support portion 20, and thus, in an assembling process of joining the lens array 100 to another lens array and the like, the lens array 100 can be precisely positioned by being supported from behind. Furthermore, a fitting portion transfer surface 83c forming the convex fitting portion 30 forms a concave portion on the center side of a die at the time of molding of the lens array 100, and thus a volume of a glass droplet, that is, heat capacity is increased, which is advantageous from a viewpoint of making molding of the optical surfaces 11a and 12a stable and highly precise, and the problems such as breakage are less likely to occur.
