A treating device according to the present invention comprises: a transmitting member for transmitting energy, for treating living body tissue, to the living body tissue; an outer sheath through which the transmitting member is passed; and a grasping section supported at the tip end portion of the outer sheath so as to be capable of turning with respect to the transmitting member, which allows the living body tissue to be grasped against the transmitting member. With such an arrangement, curved portions are formed on each of the transmitting member and the grasping section such that the transmitting member and the grasping section are in close contact. Furthermore, an edge portion is provided to a tip end portion of the transmitting member, at the side of the transmitting member in the direction toward which the grasping section heads, at the time of the grasping section turning on the turning axis toward the transmitting member so as to close.
