Disclosed herein is a magnetic powder which can provide a bonded magnet having high mechanical strength and excellent magnetic properties. The magnetic powder has an alloy composition represented by the formula of Rx(Fe1-yCOy)100-x-zBz (where R is at least one rare-earth element, x is 10 - 15at%, y is 0 - 0.30, and z is 4 - 10at%), wherein the magnetic powder includes particles each of which is formed with a number of ridges or recesses on at least a part of the surface thereof. In this magnetic powder, it is preferable that when the mean particle size of the magnetic powder is defined by a mu m, the average length of the ridges or recesses is equal to or greater than a/40 mu m. Further, preferably, the ridges or recesses are arranged in roughly parallel with each other so as to have an average pitch of 0.5 - 100 mu m.
