    摘要： There are provided: a linear motion guide device, which enhances workability of raceway surfaces and is capable of reducing production cost; and a production method for the linear motion guide device. For this purpose, a linear motion guide device includes a guide rail (1), a slider (2), and a plurality of rolling elements (4), and the guide rail (1) and the slider (2) individually have raceway surfaces (11, 21), which form a rolling path (3) of the rolling elements (4), at positions opposite to each other. Then, the rolling elements (4) are disposed in the rolling path (3), and the slider (2) moves with respect to the guide rail (1) via the rolling elements (4). The raceway surface (21) of at least one of the slider (2) and the guide rail (1) is composed of: a first raceway surface (21A); and second raceway surfaces (21B) extending on both sides of the first raceway surface (21), and surface roughness of the second raceway surfaces (21B) is set rougher than surface roughness of the first raceway surface (21A).
