[Problem] To prevent formation, from the beginning, of a crevice between the concave surface formed on the head and the sheet covering same and make it difficult for tongue coating to accumulate in said area. [Solution] For a head (1), providing a first sheet on the surface of the head (1) where a concave surface (11) is formed and fixing the sheet at the side surface (1A) of the head (1) enable the sheet facing the concave surface (11) to slide. With the head (1) as a separate piece, which is the form of the tongue coating-cleaning tool, a sheet material (4B) is disposed on the concave surface (11), after which the sheet material (4B) is pressed onto the concave surface (11) using a lower mold (14) and an upper mold (15) to adhere the sheet (4) closely to the concave surface (11) or to form a curved surface with a minimal crevice therefrom. As a result, no crevice is formed between the sheet material (4B) and the concave surface (11) or if formed, the crevice is minimal. It is therefoe difficult for tongue coating to accumulate between the sheet material (4B) and the concave surface (11) and the tool can be kept sanitary.La présente invention concerne le problème consistant à éviter la formation, dès le départ, dune crevasse entre la surface concave formée sur la tête et la feuille la recouvrant, afin de rendre difficile laccumulation de revêtement de langue dans la zone concernée. La solution proposée consiste, pour une tête (1), à fournir une première feuille sur la surface de ladite tête (1) dans laquelle une surface concave (11) est formée, et à fixer ladite feuille sur la surface latérale (1A) de la tête (1), permettant ainsi à la feuille en regard de la surface concave (11) de glisser. Avec la tête (1) en tant quélément séparé, qui constitue la forme de linstrument de nettoyage de revêtement de langue, un matériau de feuille (4B) est placé sur la surface concave (11), puis ledit matériau de feuille (4B) est comprimé sur la surface concave (11) au moyen dun mo
