A method of manufacturing hard capsules is characterized by comprising the steps of dispersing a water-soluble cellulose derivative in hot water and cooling the dispersion to effect dissolution of the water-soluble cellulose derivative in the water, adding and dissolving a gelling agent in the water-soluble cellulose derivative solution to give a capsule-preparing solution, dipping a capsule-forming pin into the capsule-preparing solution at a predetermined temperature, then drawing out the pin and inducing gelation of the capsule-preparing solution adhering to the pin.
