The present invention relates to a cleaning comb 1 with teeth 3 that are rugged on their peripheral surface and a method of manufacturing a high mechanical strength cleaning comb 1. The comb 1 includes a plurality of teeth 3 arranged parallel to each other with a spacing of under 100 µm, which are rugged on their peripheral surface for the purpose of more effectively removing foreign elements and smaller particles attached to the hair. The teeth 3 have a total length and a relatively large useful length, i.e. a portion that protrudes from the handle, and they have a diameter of over 1 mm. In order to give the comb a high mechanical strength, the method of manufacturing the comb includes attaching the teeth 3 onto the handle 2 preferably by laser welding or soft soldering. The ruggedness on the peripheral surface is provided by cutting an helical groove 9 or several parallel circumferential grooves 10 in the respective surface.
