Zusammenfassung:	A lower end vortex control plate 21 is provided to a rudder lower end surface Sd of a rudder plate 11, 5-15% of a lower end rudder length Ld toward the rear of a front end 11df on the rudder lower endsurface Sd serves as a lower end first region Rd1, 5-50% of the lower end rudder length Ld toward the front front of a rearmost end 11da on the rudder lower end surface Sd serves as a lower end second region Rd2, a front end 21f and rear end 21a of the lower end vortex control plate 21 are respectively disposed within the lower end first region Rd1 and the lower end second region Rd2, and the lower end vortex control plate 21 is formed such that a width Bdb(x) of the lower end vortex control plate 21 is 5-30% of a rudder width Bd(x) over at least 80% of the lower end vortex control plate 21 in a longitudinal direction X. As a result, a ship rudder and ship are provided that are able to relatively increase rudder force when the rudder is turned and at an angle, and that are able to conserve energy due to resistanc
