Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an oil composition for an acrylic fiber as a carbon fiber precursor that excellently maintains a fusion-proof property between single filaments and is excellent in operation stability and can obtain a carbon fiber bundle having an excellent mechanical property, and to provide an acrylic fiber bundle as a carbon fiber precursor and a method for producing the same.SOLUTION: There is provided an acrylic fiber bundle as a carbon fiber precursor having an oil composition on the surface of the fiber. The oil composition includes: 63 to 97 pts.mass of amino group-containing polydimethyl siloxane represented by formula (1), which has a dynamic viscosity of 25 to 750 mm/s (25°C) and an amino equivalent of 1000 to 8000 g/mol; and 3 to 37 pts.mass of polyoxyethylene alkyl ether represented by the following formula (2).
