The first frame50has a first portion55to which the third lens53is fitted and a second portion56where the second lens element is disposed inside the inner periphery thereof. The adhesive agent58fixes the fourth lens54to the first frame50. The material of the fourth lens54has lower stiffness than the material of the third lens53, or has a larger coefficient of linear expansion. A gap S is formed in the radial direction between the fourth lens54and the second portion56. The inside diameter of the first portion55is different from the inside diameter of the second portion56.
