1. A method for transplanting a biological constituent into a recipient, comprising enclosing a biological constituent in a chamber for transplantation,
the chamber for transplantation comprising a membrane for immunoisolation at a boundary between an inside and an outside of the chamber for transplantation,
wherein the membranes for immunoisolation face each other to form an interior space, the membranes for immunoisolation which face each other have joint portions that are joined to each other,
the interior space includes a point at a distance of 10 mm or longer from any position of the joint portion, and
the membrane for immunoisolation has flexibility that allows a distance of 1 mm to 13 mm as the following distance, measured as follows:
a portion of 10 mm from a side surface of one short side of a 10 mm×30 mm rectangular test piece of the membrane for immunoisolation is vertically sandwiched between flat plates,
the flat plates are placed horizontally, and
a distance between a horizontal plane including a center plane in a thickness direction of the sandwiched portion of the membrane for immunoisolation, and a part, which is farthest from the horizontal plane, of a residual 20 mm-portion projecting from the flat plate is measured.
