PROBLEM TO BE SOLVED: To provide a rolling bearing for a business machine which is inexpensive and has excellent corrosion resistance and conductivity. SOLUTION: The rolling bearing 1 for a business machine is equipped with an inner ring 2, an outer ring 3, and a plurality of rolling elements 4 disposed freely rollably between the inner ring 2 and the outer ring 3. At least one of the inner ring 2 and the outer ring 3 is equipped with a metal coating film 5 formed by projecting at least one of zinc powder and tin powder on at least a portion of the surface. Upon projecting, the rolling bearing 1 is fitted to a tool and fixed, and central axes of a plurality of the rolling bearings 1 are matched and side faces thereof are made to face each other so that the rolling bearings 1 are aligned in a line. The metal coating film 5 is formed by projecting the powder on the inner diameter face of the inner ring 2 and the outer diameter face of the outer ring 3 while rotating the tool or an injection nozzle.
