摘要： A method of producing a lens that includes shifting a first die relative to a second die, and pressing an optical material shaped in a preliminary form between the first die and the second die so as to form a lens having a configuration corresponding to a hollow portion formed by the first die and the second die while shifting the first die relative to the second die. The produced lens includes an effective optical surface configured to converge a light flux. The effective optical surface includes a light entrance side, a light exit side, and an optical axis. The effective optical surface is a convex surface shaped such that when a maximum normal line angle is defined as an angle formed between the optical axis and a normal line at the outermost circumference of the effective optical surface, the maximum normal angle is 60° to 90°.
