Abstract: In a Bowden cable, a shield thereof is formed from a hollow strand that is formed by twisting a plurality of metal individual wires. An end part of this hollow strand is exposed by removing an outer skin and is increased in diameter, thereby forming a first flare part. An end part of a liner is also increased in diameter to form a second flare part. An end piece is injection molded so as to envelop these flare parts. A synthetic resin as a material of this end piece is made to enter between the metal individual wires. The end piece includes a mounting part and a bent pipe part for covering and surrounding an outer periphery of an outer cable in a state in which the outer cable is curved. The mounting part and the bent pipe part are formed as a unit by injection molding.
