Abstract: A spiral wound-type separation membrane module and a method for manufacturing the same are provided. The spiral wound-type separation membrane module according to an exemplary embodiment of the present invention is implemented by including an outlet pipe; a filter assembly wound in a spiral wound on the outlet pipe; and an adhesion portion in which part or all of a heat-adhesive yarn wound to surround the outer surface of the filter assembly in the longitudinal direction of the outlet pipe is melted and fixed to the filter assembly. According to the above, the spiral wound-type separation membrane module and the method for manufacturing the same can significantly reduce the defect rate and process time and simultaneously exhibit an eco-friendly effect during disposal after use.
