Abstract: Provided is a surveying instrument configured so that the optical axis of a guide light irradiation unit that irradiates guide light for guiding a survey operator and the optical axis of a lens barrel portion of a distance-measuring optical system become parallel to each other on a horizontal plane. The guide light irradiation unit is not disposed above the lens barrel portion that substantially matches a collimation direction is horizontally shifted with respect to the lens barrel portion. The horizontal shift distance D is configured so that a horizontal distance D between the optical axis of guide light and the optical axis of the lens barrel portion satisfies tan(α/2)×Cmin>D provided that α is an irradiation angle of the guide light in the horizontal direction, and Cmin is a shortest use distance of the surveying instrument.
