PROBLEM TO BE SOLVED: To obtain a porous body having porosity and open cell properties by appropriately entanglement of fine cellulose fibers without agglomeration, and has a high specific surface area and excellent flexibility, breathability, dimensional stability, and handleability. Therefore, to provide a porous cellulose body suitable for adsorbents, heat insulating materials, sound absorbing materials and the like. SOLUTION: A cellulose porous body comprising fine cellulose fibers having an average fiber diameter of 2 to 1000 nm as a main constituent and an apparent density of 0.005 to 0.15 g / cm 3 .
