PROBLEM TO BE SOLVED: To provide a linear guide device capable of performing the positioning among an upper mounting face of a bearing block, a female screw part and a rolling face of a load rolling element with high accuracy, and reducing the noise by smoothing an inner face of a rolling element circulating passage. SOLUTION: In this linear guide device, an outer rolling face 15 is formed on an inner face of a U-shaped guide rail 2, inner rolling faces 16 are formed on both side faces of a bearing block body 12, an axial female screw part is formed on an approximately central part of the bearing block body 12, rolling elements (ball chain 54) are respectively mounted between the outer rolling face 15 and each of the inner rolling faces 16, and a screw shaft 4 is engaged with the female screw part 12 of the bearing block body 12. A female screw body 12' having the female screw part 12 is integrally molded in a prepared hole of the female screw part of the bearing block body 21 by, for example, molding and processing a synthetic resin.
