Honeycomb structure and heat exchanger

Abstract

A honeycomb structure includes: an inner peripheral wall; an outer peripheral wall; and partition walls disposed between the inner peripheral wall and the outer peripheral wall, the partition walls defining a plurality of cells each extending from a first end face to a second end face. In a cross section orthogonal to an extending direction of the cells, the partition walls include one or more first partition walls extending in a radial direction. The inner peripheral wall and the outer peripheral wall have an average thickness of 0.1 mm or more, and a thickness variation coefficient of 1.0 or less, represented by the following equation (1): the thickness variation coefficient=a standard deviation of the thicknesses of the inner peripheral wall and the outer peripheral wall/an average thickness of the inner peripheral wall and the outer peripheral wall  (1).
