1. A heat exchange member, comprising:
a honeycomb structure comprising: an outer peripheral wall; an inner peripheral wall; and partition walls arranged between the outer peripheral wall and the inner peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from a first end face to a second end face to form a flow path for a first fluid; and
a covering member for covering an outer peripheral surface of the outer peripheral wall,
wherein in a cross section of the honeycomb structure orthogonal to a flow path direction for the first fluid, the partition walls extend in a radial direction,
wherein each of the cells is formed from the outer peripheral wall, the inner peripheral wall, and the partition walls, and
wherein, in the cross section of the honeycomb structure orthogonal to the flow path direction for the first fluid, a ratio of the number of the partition walls to an outer diameter (mm) of the honeycomb structure is 2.3 partition walls/mm or more.
