Beschreibung
Zusammenfassung:	[Problem]The purpose of the invention is to improve adhesion of a catalyst layer and an oxide film in a honeycomb substrate for catalyst support.[Solution]A honeycomb substrate for catalyst support used in purification of exhaust gas is characterized by comprising a honeycomb body and an oxide film that is formed on the surface of the honeycomb body and that has α-alumina as a main component, and in that the oxide film includes multiple oxide projections that are formed to be dispersed on the film surface and that comprise a contracted shape in which the width becomes narrower near the honeycomb body, and the density of the projection formations on the film surface is 0.20 (pieces/µm2) - 3.00 (pieces/µm2).
