PROBLEM TO BE SOLVED: To provide a printed wiring board which suppresses or eliminates generation of a dimension error, shape distortion, and deformation of a flying lead arranged to project to a device hole, and to provide a method of manufacturing the same. SOLUTION: The printed wiring board includes a wiring 2, a device hole 4, and the flying lead 3 connected to the wiring 2 and arranged to project to the device hole 4 on a surface of an insulating base 1. The device hole 4 includes first device holes 5 (5a, 5b, 5c) arranged to include at least a tip end of the flying lead 3, and a second device hole 6 having a larger area than the first device holes 5 and arranged to continue at least partially to the first device holes 5.
