Abstract
An object is to provide a distance measurement device capable of receiving measurement light reflected by an object by responding to a wide angle range with a high S/N ratio. The object is achieved by the distance measurement device including: an infrared light source; a light receiving section that receives an infrared ray emitted from the light source and reflected by an object; and a band-pass filter (BPF) member that is disposed on a light-receiving surface side of the light receiving section and through which the infrared ray is transmitted, in which the BPF member includes a BPF and a refraction member that is disposed in contact with the BPF and refracts the infrared ray.
