PROBLEM TO BE SOLVED: To provide a linear guide suppressing damage even if driven at high speed, and having excellent durability. SOLUTION: The linear guide comprises a guide rail 1 having a rolling element rolling groove 10 extending in an axial direction on an outer surface; a slider 2 having a rolling element rolling groove 11 opposite to the rolling element rolling groove 10 of the guide rail 1, and attached to the guide rail 1 so as to move in the axial direction; a plurality of rolling elements 3 filled in a rolling element rolling path 14 formed between both rolling element rolling grooves 10, 11 so as to freely roll; and a rolling element returning path 16 sending a rolling element 3 from an end point to a start point of the rolling element rolling path 14. A rolling element scooping-up portion 17 guiding the rolling element 3 positioned at the end point of the rolling element rolling path 16 into the rolling element rolling path 16 is provided. A tip end portion 17a of the rolling element scooping-up portion 17, with which the rolling element 3 collides is formed in a plane vertical to the rolling element rolling path 14.
