PROBLEM TO BE SOLVED: To provide: a nonwoven fabric for a semipermeable membrane support in which MD curling is excellent when a semipermeable membrane coating liquid is coated to a support (nonwoven fabric), and is cured; and a method of manufacturing the same.SOLUTION: A nonwoven fabric for a semipermeable membrane support is a nonwoven fabric mainly composed of an organic synthesis fiber. In the nonwoven fabric for a semipermeable membrane support in which a semipermeable membrane is supported on one surface of the nonwoven fabric, when the nonwoven fabric on which a semipermeable membrane is coated is peeled to two layers in a thickness direction and thus is divided to a semipermeable membrane coating side layer and a semipermeable membrane non-coating side layer, the semipermeable membrane coating side layer accounts for 35 mass% to 70 mass% of the total of the semipermeable membrane coating side layer and the semipermeable membrane non-coating side layer. |
