1. An optical module, comprising:
a substrate;
a light emitting element on the substrate;
a light receiving element on the substrate at a specific interval from the light emitting element;
a first casing on the substrate, wherein the first casing surrounds a periphery of the light emitting element;
a second casing on the substrate, wherein the second casing surrounds a periphery of the light receiving element;
a light emitting lens in the first casing, wherein the light emitting lens is on a first optical axis of the light emitting element; and
a light receiving lens in the second casing, wherein the light receiving lens is on a second optical axis of the light receiving element, wherein
a first diameter of one lens out of the light emitting lens or the light receiving lens in a first direction is shorter than a second diameter of the one lens in a second direction,
the second direction is orthogonal to the first direction,
the first diameter is toward a third optical axis of another lens of the light emitting lens or the light receiving lens, with reference to a fourth optical axis of the one lens, and
the first diameter is equal to or greater than an effective diameter of the one lens.
