A dysphonia treatment tool (X) comprising: one or more sets of one pair of clamping sections each including a front surface piece having a base end side and a distal end side and formed into a substantially strip-like plate shape in a planar view, said front surface piece to be disposed from a cut end surface of thyroid cartilage incised to a front surface; and a rear surface piece to be disposed on a rear surface of the thyroid cartilage, and to be fitted respectively to cut ends of the thyroid cartilage that are opposite each other; and a bridging section linking the one or more sets of one pair of clamping sections to each other, wherein a part on a base end side in a longitudinal direction (m) of the front surface piece forms an end surface section that is bent and adapted to be brought into contact with the cut end surface of the thyroid cartilage, and wherein a part on the distal end side of the front surface piece with respect to the end surface section forms a front surface contacting section that is adapted to be brought into contact with a front surface of the thyroid cartilage, wherein a plurality of holes is formed in the front surface contacting section of the front surface piece at an interval in the longitudinal direction (m), characterized in that an intermediate section between the distal end side and the base end side of the front surface contacting section is bent to a rear surface piece side with an imaginary line L which is substantially at center of the bending and between the holes and substantially orthogonally crosses an array direction of the holes so as to form a bend angle of equal to or greater than 10 degrees and equal to or less than 50 degrees, wherein the bend angle is an angle formed by flat plates adjacent to each other sandwiching a bent part. one or more sets of one pair of clamping sections each including a front surface piece having a base end side and a distal end side and formed into a substantially strip-like plate shape in a planar view, said front surface piece to be disposed from a cut end surface of thyroid cartilage incised to a front surface; and a rear surface piece to be disposed on a rear surface of the thyroid cartilage, a front surface piece having a base end side and a distal end side and formed into a substantially strip-like plate shape in a planar view, said front surface piece to be disposed from a cut end surface of thyroid cartilage incised to a front surface; and a rear surface piece to be disposed on a rear surface of the thyroid cartilage, and to be fitted respectively to cut ends of the thyroid cartilage that are opposite each other; and a bridging section linking the one or more sets of one pair of clamping sections to each other, wherein a part on a base end side in a longitudinal direction (m) of the front surface piece forms an end surface section that is bent and adapted to be brought into contact with the cut end surface of the thyroid cartilage, and wherein a part on the distal end side of the front surface piece with respect to the end surface section forms a front surface contacting section that is adapted to be brought into contact with a front surface of the thyroid cartilage, wherein a plurality of holes is formed in the front surface contacting section of the front surface piece at an interval in the longitudinal direction (m), characterized in that an intermediate section between the distal end side and the base end side of the front surface contacting section is bent to a rear surface piece side with an imaginary line L which is substantially at center of the bending and between the holes and substantially orthogonally crosses an array direction of the holes so as to form a bend angle of equal to or greater than 10 degrees and equal to or less than 50 degrees, wherein the bend angle is an angle formed by flat plates adjacent to each other sandwiching a bent part. <EOS>
