According to the present invention, there are provided a chamber for transplantation which has a high durability, and in which an enclosed biological constituent can be maintained for a long period of time because an interior space thereof is efficiently secured; and a method for manufacturing the chamber for transplantation. The chamber for transplantation includes one or more membranes for immunoisolation at a boundary between an inside and an outside of the chamber for transplantation, in which all of the membranes for immunoisolation include a porous membrane containing a polymer, and a joint portion at which the porous membranes are directly fusion welded to each other is provided. The method for manufacturing a chamber for transplantation includes preparing one or more porous membranes containing a polymer selected from polysulfone and polyethersulfone, bringing one part of the porous membrane into direct contact with another part of the porous membrane, and performing a heat fusion welding of the two parts that are in direct contact with each other at a temperature which is a glass transition temperature of the polymer or higher and lower than a melting point of the polymer.
