    摘要: An objective lens for use in an optical pickup apparatus, comprises a first lens molded with a plastic and having an optically functional section, flange section provided around the periphery of the optically functional section, and a first contacting section provided on the flange section; and a second lens molded with a plastic, located opposite to the first lens and having an optically functional section, a flange section provided around the periphery of the optically functional section, and a second contacting section provided on the flange section. The first lens and the second lens are joined in such a way that the first contacting section and the second contacting section are brought in contact with each other.
