An optical module ( 100 ) includes a lens barrel ( 10 ), a lens ( 201 ), a filter ( 40 ), and a groove ( 105 ). The lens is engagingly received in the lens barrel. The filter is engagingly received in the lens barrel with an adhesive. The groove is defined in the lens barrel. The groove is adjacent to an outer periphery of the filter to receive the adhesive so as to prevent it from infiltrating into the lens.
