摘要： An objective lens for an optical pickup apparatus is disclosed that can record and/or reproduce information compatibly for different optical discs with stability regardless of an environmental temperature change, in spite of its simple structure, and provides an optical pickup apparatus employing the objective lens. The objective lens includes: an optical surface which at least includes a central area, a peripheral area, and a most peripheral area. The objective lens is a single lens formed of plastic. The central area includes a first optical path difference providing structure. The peripheral area includes a second optical path difference providing structure. The objective lens further includes an optical path difference providing structure for correcting a temperature characteristic, where the optical path difference providing structure corrects an aberration caused by a temperature change of the objective lens.
