PROBLEM TO BE SOLVED: To provide a lens component which is easily injection-molded and does not cause occurrence of a weld line in lens parts.SOLUTION: A lens component comprises: a lens area 60 in which a plurality of element side lens parts 62 are formed along one-way; a thin wall part 61 extending from the lens area 60 in a direction crossing the arrangement direction of the element side lens parts 62; a single gate trace 70 formed on the opposite side to the lens area 60 with the thin wall part 61 therebetween; a pair of first thick wall parts 72 formed thicker than the thin wall part 61 on both sides of the thin wall part 61 and extending from the side of the gate trace 70 to the side of the lens area 60; and a second thick wall part 73 formed thicker than the thin wall part 61 on the opposite side to the side of the gate trace 70 of the lens area 60 and continuing to the pair of first thick wall parts 72. A weld line WL is formed at a position not crossing the element side lens parts 62. |
