[PROBLEMS] To provide a resin composition that has few aggregates when blended with a plasticizer, is excellent in transparency, and is superior in transparency and mechanical strength when blended with a thermoplastic resin or a curable resin. The present invention relates to a fine cellulose fiber composite to be obtained, and a fine cellulose fiber composite dispersion containing the composite and a resin composition. SOLUTION: Fine cellulose fibers in which an amine having an ethylene oxide / propylene oxide (EO / PO) copolymer part is bonded as a salt to a carboxy group of fine cellulose fibers having a carboxy group content of 0.1 mmol / g or more. A fine cellulose fiber composite having a molecular weight of 700 to 10,000 in the EO / PO copolymer part and a PO content of 1 to 70 mol% in the EO / PO copolymer part. . [Selection figure] None |
