A membrane module which enables products with more stable and uniform qualities to be produced during manufacturing of a large module, causes an undiluted solution to be uniformly supplied to a plurality of membranes, and has an excellent cleaning effect of the membranes, and a manufacturing method of the same are provided. A membrane module(100) comprises: a hollow outer cylinder(110); a plurality of membranes(120); a plurality of lower fixed caps which are formed in a polygonal cross-sectional shape, and have undiluted solution-and-air inflow pipes(131) formed at an approximately central part thereof, wherein both ends of the undiluted solution-and-air inflow pipes are opened to supply an undiluted solution and air through the undiluted solution-and-air inflow pipes; a top adhesion part(140) formed by applying an adhesive onto the top of the membranes; a bottom adhesion part(150) which is formed by applying an adhesive onto the bottom of the membranes, and has a plurality of undiluted solution-and-air supply holes formed on an outer peripheral surface thereof; a concentrated liquid discharge pipe(160) of which both ends are opened, and which is formed in a cylindrical shape to discharge contaminants to the outside; an upper connection member(170) connected to an upper part of the plurality of membranes to discharge filtered liquid passing through the plurality of membranes to the outside; and a lower connection member(180) which is connected to a lower part of the plurality of membranes, and through which an undiluted solution and air are supplied.
