To reduce frictional resistance against hair, make comfortable to use, make the comfortableness last long and make dirt resistant by containing a boron nitride in the part of the subject device that contacts hair.

When containing a boron nitride in a structure forming the part of a comb or brush type hair grooming device that contacts hair, if a substance other than the boron nitride forming the part of the hair grooming device that contacts hair is the one such as a resin or the like that has plasticity under a certain condition, a product is obtained by mixing a boron nitride of a crystalline powder form into a plastic structural substance and molding. The surface of the part of the comb or brush type hair grooming device that contacts hair may be coated with a boron nitride. If the part of the comb or brush type hair grooming device that contacts hair is a sintered body such as ceramics or the like, it is contained by sintering and molding a boron nitride of a crystalline powder form together with other sintered materials.
