**Abstract** In the research and development of CNF, the use of electron microscopy for observation has become a necessary evaluation across almost all material fields and research phases. Particularly for observing CNF dispersed in polymers using TEM, it is essential to employ the technique of "electron staining," which has been crucial for preparing TEM samples of polymer materials. In this presentation, we will introduce examples of morphological observations of composite materials using CNF, as well as observation cases of the CNF itself, structural analysis examples such as crystallinity measured by 13C solid-state NMR, and examples of compositional sugar analysis using acid hydrolysis HPLC-fluorescence detection. **Table of Contents** 1. Introduction 2. Overview of Morphological Observation 3. Observation Cases of CNF and CNF/Polymer 4. Evaluation of CNF Crystallinity 5. Compositional Sugar Analysis of CNF (HPLC-Fluorescence Detection) 6. Conclusion
