Light module

A light module comprising:

• an optical element;
• and
• a base on which the optical element is mounted,
• wherein the optical element has
• an optical portion which has an optical surface,
• an elastic portion which is able to be elastically deformed, and
• a pair of support portions which is provided to face each other 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,
• wherein the base has a main surface, and a mounting region in which an opening communicating with the main surface is provided,
• wherein the pair of support portions is inserted into the opening in a state where an elastic force of the elastic portion is applied, and
• wherein the optical element is supported in the mounting region by a reaction force of the elastic force applied from an inner surface of the opening.
