The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens includes, from an object side to an image side: a first lens made of a plastic material; a second lens made of a plastic material; a third lens made of a plastic material; a fourth lens made of a glass material; a fifth lens made of a glass material; a sixth lens made of a plastic material; and a seventh lens made of a plastic material. The camera optical lens satisfies following conditions: 1.51≤f1/f≤2.50; 1.70≤n4≤2.20; 2.00≤f3/f4≤5.00; −10.00≤(R13+R14)/(R13−R14)≤10.00; and 1.70≤n5≤2.20. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
