Abstract
A lens module includes an optical turning unit and a lens unit. The optical turning unit includes a reflecting surface. The lens unit includes a lens barrel and a lens constituting an optical axis, and the lens barrel includes a first end portion adjacent to the optical turning unit. The reflecting surface and the optical axis meet at an intersection point, a distance from the intersection point to the lens is a fourth length, a distance from the intersection point to the first end portion is a fifth length, and a normal line of the reflecting surface is sloped at a first angle with respect to the optical axis. The lens module satisfies: 0.8<tan (α)×A'/B′<1, α is the first angle, A′ is the fourth length, and B′ is the fifth length.
