Honeycomb structure and method for manufacturing same

Abstract

A honeycomb structure which is an aggregate of a plurality of microtubes comprising a cellulose nanofiber, wherein the microtubes have an opening shape which is polygonal, wherein the ratio of an average long diameter μ2 (μm) to an average short diameter μ1 (μm) (μ2/μ1) is 2.0 or less, when the average long diameter μ2 (μm) is an average of longest diameters of the opening diameters of the individual microtubes, and the average short diameter μ1 (μm) is an average of shortest diameters of the opening diameters of the individual microtubes, and wherein both standard deviations σ1, σ2 for the respective frequency distributions of the short diameter and long diameter in the opening shape of the microtubes are 20.0 μm or less.
