L'objectif de la présente invention est de fournir une brosse à dents qui peut réaliser un effet de nettoyage de l'intérieur de la bouche et une amélioration de la résistance à l'évasement des poils sans entraîner une augmentation des coûts ou une diminution de la productivité. L'invention concerne une brosse à dents qui est équipée d'une partie de tête (10) dans laquelle une pluralité de trous d'implantation 12 sont disposés dans une surface d'implantation (11). Un faisceau de poils est implanté dans chaque trou d'implantation à l'aide d'un fil plat (6) qui est pris en sandwich par un faisceau de poils plié et qui est poussé dans l'intérieur du trou d'implantation. L'épaisseur de la partie de tête est de 2 à 4,5 mm. La profondeur maximale des trous d'implantation est de 1,5 à 4,0 mm. Chaque trou d'implantation a une zone non occupée de fil plat (NA) qui est sur le côté de surface d'implantation au-dessus d'un côté supérieur (6a) du fil plat, qui fait face au côté supérieur, et qui n'est pas occupée par le fil plat. La hauteur de la zone non occupée de fil plat dans la direction de profondeur des trous d'implantation est de 0,5 à 0,8 mm.
