To provide an optical pickup of a high NA, having both good on-axis characteristics and good off-axis characteristics and securing a longer working distance.

The optical pickup lens 1a is a double convex single lens where a numerical aperture NA is larger than 0.80, and an R1 surface 11 close to a laser light source and an R2 surface 12 opposite thereto are convex. Of the two surfaces, the shape of the R2 surface 12 has a continuous shape. When radiuses h1, h2 and h3 (h1h2h3) are set from an optical axis toward a lens outer diameter, when sag amounts in the radiuses h1, h2 and h3 are respectively sag1, sag2, and sag3, and change amounts of the sags are sag1, sag2, and sag3, there are h1, h2, and h3 which satisfy 0sag1sag2, and sag2/sag3, and a refractive index n at a wavelength of 405 nm is 1.59n1.62.
