Even when changing the thickness and production conditions of the porous support to be used and provides a composite semipermeable membrane, the separation membrane element using the same that can maintain a sufficient blocking property and a method of manufacturing the same. In the composite semipermeable membrane having a separation function on the surface of the porous support having a polymer porous layer on one surface of the nonwoven fabric layer layer, wherein the porous support is, for the relationship between the size and frequency of defects determined from the transmitted light, the polymer film-forming line of the porous layer the frequency F1 of the defect perpendicular to the width direction of not less than 0.3 ㎜ is characterized in that not more than 50/480 ㎡.
