PROBLEM TO BE SOLVED: To provide a method for simply producing fine cellulose fiber-containing dry solids excellent in redispersibility in a solvent such as water， without using higher heat energy and additives. SOLUTION: A method for producing fine cellulose fiber-containing dry solids includes a step of drying at a relatively low temperature under low pressure conditions. Since fine cellulose fiber-containing dry solids produced according to one aspect of the present invention contain fine cellulose fibers having a content of introduced sulfur atoms derived from sulfo groups of 0.5 mmol/g or more， the redispersion liquid is excellent in redispersibility from the viewpoint of transparency， viscosity characteristics and precipitation characteristics.
