Abstract
As a result of a fourth surface being a surface on a gate side, a merging position of a molten resin material during molding of a lens array main body is placed away from formation positions of lens faces, and as a result of the three dimensional shape of a third recessing section, during molding of the lens array main body, the flow of molten resin material from a surface side that opposes the fourth surface into a flow path corresponding with an area between a first recessing section and a second recessing section can be suppressed.
