Provided is a lens array that can be easily positioned when fixing the lens array to other components, and that is less likely to cause problems such as lens cracking during manufacturing. Since the convex fitting part 30 is provided on the center side and protrudes from the support part 20, in the assembly process for joining the lens array 100 to another lens array or the like, the lens array 100 is supported from the back side and precisely. It becomes possible to position. Further, the fitting portion transfer surface 83c forming the convex fitting portion 30 forms a concave portion on the center side of the mold when the lens array 100 is molded, so that the volume of the glass droplet, that is, the heat capacity is increased. That is, it is advantageous from the viewpoint of stabilizing the molding of the optical surfaces 11a and 12a and increasing the accuracy, and problems such as cracking are less likely to occur.
