Abstract
A heat generating device includes a honeycomb structure, a first electrode, and a second electrode. The honeycomb structure includes an outer wall and partition walls. The partition walls define a plurality of cells extending from a first end surface to a second end surface. The first electrode is provided on a profile surface of the honeycomb structure. The second electrode is provided on the profile surface, and is located away from the first electrode. The profile surface includes: a first portion located between the first electrode and the second electrode; and a second portion located on a side opposite to the first portion with respect to a center of a cross section of the honeycomb structure taken along a direction orthogonal to an extending direction of the cells. The honeycomb structure has a first slit. The first slit extends from the first portion toward the second portion.
