Seamless knitwear of mixed set-in and raglan sleeves, and a method of knitting the same seamless knitwear. The knitwear of the present invention comprises a body and sleeves. A front body of the body has armhole parts and shoulder-line parts extending along one's shoulder line formed when wearing the knitwear, and a back body of the body has slant-line parts extending obliquely from neckline to side parts of the body. The front and back bodies are knitted in tubular form in a seamless manner, and the sleeves are knitted in tubular form in a seamless manner. The sleeves are joined to the armhole parts, the shoulder-line parts, and the slant-line parts of the front and back bodies in a seamless manner, and a neckline is formed by a part of the sleeves. The number of courses of the front and back bodies knitted in the course of joining of the sleeves to the armhole parts of the bodies is set so that the number of course of the back body knitted is decreased below the number of courses of the front body knitted. The number of courses of the front and back bodies knitted in the course of joining of the sleeves to the shoulder-line parts of the bodies is set so that the number of course of the back body knitted is increased over the number of courses of the front body knitted.
