Zusammenfassung:	(1) 1.0질량%의 CNF 수분산액을 준비하는 공정과, (2) CNF 수분산액에 색재를 첨가하고, 볼텍스 믹서로 교반하는 공정과, (3) 색재를 함유하는 CNF 분산액의 막 두께가 0.15mm가 되도록 2매의 유리판에 끼우는 공정과, (4) 2매의 유리판에 끼운 색재를 함유하는 CNF 수분산액의 막을 현미경으로 관찰하는 공정과, (5) 관찰된 응집물을 그 크기(장경)에 의해 분류하는 공정과, (6) 분류한 응집물의 개수로부터 CNF 분산 지수를 산출하여, CNF 수분산액의 분산성을 평가하는 공정을 포함하는 CNF 분산액의 평가 방법. Provided is method for evaluating a cellulose nanofiber (CNF) dispersion, the method including: (1) a step of preparing 1.0 mass% of a CNF aqueous dispersion; (2) a step of adding a coloring material into the CNF aqueous solution and stirring with a vortex mixer; (3) a step of sandwiching a film of the coloring material-containing CNF aqueous dispersion between two glass plates such that said film has a thickness of 0.15 mm; (4) a step of observing, with a microscope, the film of the coloring material-containing CNF aqueous dispersion sandwiched between the two glass plates; (5) a step of sorting observed aggregates by size (diameter along major axis) thereof; and (6) a step of calculating a CNF dispersion index from the number of sorted aggregates and evaluating the dispersibility of the CNF aqueous dispersion.
