Claim Text:
1. A light emitting module, comprising: a substrate; at least one light emitting element line including a plurality of light emitting elements that are arrayed on the substrate in a first direction; and at least one sealing lens sealing the at least one light emitting element line, and including a plurality of lens sections, the lens sections each including a spherical light emission surface having a convex shape, and being provided corresponding to the respective light emitting elements and continuous in the first direction, the lens sections include a first lens section and a second lens section that correspond to a first light emitting element and a second light emitting element adjacent to the first light emitting element respectively, the second lens section is adjacent to the first lens section, the lens sections each satisfy the following expressions (1) and (2): wherein Dp is a pitch width of the light emitting elements in the first direction, R is a curvature radius of the light emission surface of any of the lens sections, and θ is an angle in degree (°), in a cross section perpendicular to the substrate taken along the first direction, of a virtual straight line to a central axis of the first light emitting element, the virtual straight line connecting a contact point and a central point, the contact point is located where a first light emission surface of the first lens section is brought into contact with a second light emission surface of the second lens section, and the central point being located on the central axis of the first light emitting element at a center of a light emission surface of the first light emitting element, the central axis is perpendicular to the first direction.
