A laser radar device includes: a pulse laser that outputs transmission light to a target; an transmission optical system that makes the transmission light at a predetermined beam spread angle; a light-receiving element array that receives scattered light from the target and converts the light to an electric signal; an electric circuit array that detects a reception intensity and a reception time from the electric signal; a range/three-dimensional shape output unit that measures a range to the target or a three-dimensional shape of the target on the basis of the reception time; a determination unit that determines whether the beam spread angle is changed or not on the basis of the reception intensity and the reception time; and a control unit that changes the beam spread angle on the basis of a determination result.
