PROBLEM TO BE SOLVED: To provided a spinning apparatus capable of stably spinning fibers having a small fiber diameter with a high productivity, an apparatus containing the same for manufacturing a nonwoven fabric, the process for manufacturing a nonwoven fabric using the nonwoven fabric manufacturing apparatus, and a nonwoven fabric produced by the process. SOLUTION: The spinning apparatus comprises one or more exits for extruding liquid, which are capable of extruding a spinning liquid, and one or more exits for ejecting gas, which extend linearly and are located upstream of each of the exits for extruding liquid and which are capable of ejecting a gas wherein a shearing force by the gas and its accompanying airstream can be single-linearly exerted on the spinning liquid extruded. The apparatus for manufacturing a nonwoven fabric comprises a fiber collection means as well as the spinning apparatus. The process for manufacturing a nonwoven fabric is a process using the apparatus for manufacturing a nonwoven fabric. The nonwoven fabric is a nonwoven fabric produced by the process.
