PROBLEM TO BE SOLVED: To provide a cylindrical bearing member capable of holding lubricating oil filled in an oil storing blind groove for a long time to sufficiently show the lubricating function thereof, and to provide a cylindrical bearing member manufacturing method capable of efficiently mass-producing the oil storing blind groove inside a cylindrical member at low cost. SOLUTION: This cylindrical bearing member 100 is manufactured by forming a steel strip 110, which is formed with multiple oil storing blind grooves 121 by pressing or roll-forming, into a tubular member, in which the oil storing blind grooves 121 are arranged inside and a bus-like joint is eliminated, by a pipe-in-coil method, and cutting it at the predetermined length.
