Abstract: The present invention aims at providing a tongue cleaner which can be used with one hand without damaging an inside surface of a roof of the mouth. A tongue cleaner of the present invention comprises a head 1, and a rod-shaped handle 3 connected to one end of the head 1. The tongue cleaner includes, on either its front or its back face, a flat and thin head with a concavely curved face having a valley portion extending parallel to a longitudinal direction of the rod-shaped handle, and a woven textile 4 having a roughened surface, serving as a sheet having a porous or multi-gap structure, attached to the concavely curved face 1a. When cleaning both sides of a tongue, the concavely curved face 1a of the head 1 is used. The head 1 can be moved back and forth while pressing it against a tongue, without causing any concerns for possible lateral displacement of the head on the surface of the tongue and without causing nausea during the cleaning.
