摘要：
A concave lens as an optical component is made of glass containing 20 to 22% of B2O3, 30 to 40% of La2O3, and 19 to 25% of ZnO, expressed as wt %. The concave lens has a thickness t1 in its center portion of 0.5 mm or less, and a ratio (W/t1) of a diameter W with respect to the thickness t1 of 24 or more. The concave lens can be produced suitably by press forming.
