The linear guide device has a structure in which a solid lubricating film is applied on the ball guide grooves of the main rail and the ball circulating paths of the slider, and the surfaces of the balls housed to be rotatable and movable in the ball circulating paths, are formed porous. Thus, when the slider is urged to move with respect to the main rail, and the balls rotate and move within the ball circulating paths, the balls are brought into contact with the solid lubricating films on the ball circulating paths and the films on the ball guide grooves of the main rail. Due to the effect of the surfaces of the balls, the solid lubricating film is transferred onto the surfaces of the balls, thus achieving solid lubrication.
