The invention relates to a composite type bearing in which bearing portions (11a, 12a) slidably supporting a rotary axis (S) are provided in both ends in an axial direction, and a middle escape portion (15) not being in contact with the rotary axis and a cylindrical magnet (13) are provided between the bearing portions (11a, 12a). The composite type sintered porous bearing is characterized in that at least two cylindrical sintered porous members (11, 12, 14) are fitted and joined so as to be united, and the magnet (13) is assembled within an outer peripheral space (16) in which an outer diameter between both end sides in an axial direction is formed to be smaller than an outer diameter of the both end sides.
