PROBLEM TO BE SOLVED: To provide an optical element which can be mounted with a high precision independently of dimensions of an effective diameter and to provide a method of mounting the same and an optical module having the optical element mounted with a high precision. SOLUTION: A lens element 1 comprises an optical substrate and has a lens part 2, two adaptation parts 4a and 4b, and a handling part 6. The adaptation parts 4a and 4b are placed in the right and the left apart from the lens part 2 and have approximately semicylindrical shapes protruding downward from the handling part 6 and partially form cylindrical shapes having major axes parallel with the optical axis of the lens part 2. Dimensions of outside diameters of arcuate shapes of adaptation parts 4a and 4b are equal to those of an optical fiber to which the lens element 1 is optically coupled. When the lens element 1 is mounted on a support substrate having grooves for mounting, the adaptation parts 4a and 4b are brought into contact with the grooves for mounting, thereby, the lens element 1 is positioned in a direction perpendicular to the optical axis.
