An optical glass includes, in terms of mol % of cations, a total amount of La3+, Y3+, and Gd3+ components falling within a range of from 5% to 65% and a total amount of Zr4+, Hf4+, and Ta5+ components failing within a range of from 5% to 65%, and a relationship expressed in Expression (1) given below is satisfied. (La3++Y3++Gd3+)×(Zr4+ Hf4++Ta3+)≥400(%)2.
