The invention provides a semipermeable composite membrane that reduces an environmental load, and a method of producing the semipermeable composite membrane. A semipermeable composite membraneincludes, on a porous support, a semipermeable membranecontaining a crosslinked polyamideand a cellulose nanofiber. A method of producing the semipermeable composite membrane includes obtaining a mixed solution containing the cellulose nanofiber, water, and an amine component, and obtaining the semipermeable composite membraneby making the mixed solution be in contact with the porous support, thereafter, causing a cross-linking reaction of the amine component in the mixed solution, with the amine component adhering to the porous support
