Objective lens and optical pick-up apparatus

fF/f≦−1.1 LH1H2/f≧0.5 fB/f≧0.2 L/f≦1.3 H1H2 An objective lens has a first meniscus-shape lens including a first object-side surface having a positive reflective power; and a second meniscus-shape lens having a positive reflective power. The first meniscus-shape lens and the second meniscus-shape are arranged in that order from an object side. The objective lens satisfies the following formulas: where f is an object-side focus length of the objective lens, fF is a front focus, fB is a back focus, Lis a length between an object-side principal point H and an image-side principal point H and L is a length on an optical axis of the objective lens between the first object-side surface and the second image-side surface.
