Abstract: A light module includes an optical element and a base on which the optical element is mounted. The optical element has an optical portion which has an optical surface; an elastic portion which is provided around the optical portion such that an annular region is formed; and a pair of support portions which is provided such that the optical portion is sandwiched in a first direction along the optical surface and in which an elastic force is applied and a distance therebetween is able to be changed in accordance with elastic deformation of the elastic portion. The base has a main surface, and a mounting region in which an opening communicating with the main surface is provided. The support portions are inserted into the opening in a state where an elastic force of the elastic portion is applied.
