Summary:PROBLEM TO BE SOLVED: To provide a technology of producing high-ash paper with high yield. SOLUTION: A method of manufacturing paper includes injecting and mixing one or more kinds of chemicals for making a paper into a paper material by using an injector 33 including a multi-fluid nozzle of a concentric structure, wherein the concentration of a liquid injected from an outermost nozzle of the multi-fluid nozzle is 0.1-2.0% by weight, and the concentration of a liquid injected from an innermost nozzle of the multi-fluid nozzle is lower than that of the liquid injected from the outermost nozzle by 0.1% by weight or less.
