A non-magnetic member, a first magnetic member and a second magnetic member are prepared. The first magnetic member and the second magnetic member are connected to the non-magnetic member. Then, a first bonding portion which bonds the non-magnetic member and the first magnetic member to each other, and a second bonding portion which bonds the non-magnetic member and the second magnetic member to each other are formed. A hot isostatic pressing process is performed to the non-magnetic member, the first magnetic member and the second magnetic member to establish diffusion-bond. Thereafter, the non-magnetic member, the first magnetic member and the second magnetic member are hollowed, and the first bonding portion and the second bonding portion are removed. Thereafter, the non-magnetic member becomes a non-magnetic body, the first magnetic member becomes a first magnetic body, the second magnetic member becomes a second magnetic body and a sleeve is obtained.
