While arbitrarily selecting the height of the lens, the lens is formed in a uniform and desired shape. Thus, the distance between the lens and another optical member can be reduced and the pitch of the lens can be reduced. ## Claims ### Claim 1 A method of producing a substrate with a lens, comprising: a first of forming a columnar member on one surface of a substrate wherein the substrate comprises a substrate comprising a through hole, and wherein the first step comprises: laminating a photosensitive resin composition for forming a columnar member from the one surface side of the substrate, and at the same time, filling the through hole, and laminating a resin composition for forming a transparent member from another surface side of the substrate, and at the same time, filling the through hole; exposing and curing a portion of the photosensitive resin composition for forming a columnar member, which matches with the through hole, and photocuring or thermosetting the resin composition for forming a transparent member; and developing and removing an uncured portion of the photosensitive resin composition for forming a columnar member to form the columnar member protruding from an inside of the through hole toward an outside of the one surface of the substrate; a second step of laminating, on the one surface side of the substrate, a photosensitive resin composition for forming a lens member to arrange the photosensitive resin composition for forming a lens member on the columnar member and on the substrate, and curing by exposure the photosensitive resin composition for forming a lens member on the columnar member to form a lens member on the columnar member; and a third step of heating the columnar member for forming a lens member to cause dripping thereof, thereby forming an upper surface thereof into a convex lens surface. ### Claim 2 (depends on 1) A method of producing a substrate with a lens according to claim 1, wherein the first step comprises arranging a mask having an opening portion at a location opposed to the through hole on another surface side of the substrate, and radiating an active light beam from the another surface side via the mask to expose and cure the photosensitive resin composition for forming a columnar member. ### Claim 3 (depends on 1) A method of producing a substrate with a lens according to claim 1, wherein the substrate exhibits light shielding performance against an active light beam in exposing the photosensitive resin composition for forming a columnar member, and wherein the first step comprises radiating the active light beam from another surface side of the substrate to expose and cure a portion of the photosensitive resin composition for forming a columnar member, which matches with the through hole. ### Claim 4 (depends on 1) A method of producing a substrate with a lens according to claim 1, wherein the second step comprises arranging a mask having an opening portion at a location opposed to the through hole on another surface side of the substrate, and radiating an active light beam from the another surface side via the mask to expose and cure the photosensitive resin composition for forming a lens member. ### Claim 5 (depends on 1) A method of producing a substrate with a lens according to claim 1, wherein the substrate exhibits light shielding performance against an active light beam in exposing the photosensitive resin composition for forming a lens member, and wherein the second step comprises radiating the active light beam from the another surface side of the substrate to expose and cure a portion of the photosensitive resin composition for forming a lens member, which matches with the through hole. ### Claim 6 (depends on 1) A method of producing a substrate with a lens according to claim 1, wherein the resin composition for forming a transparent member comprises a photosensitive resin composition.
