Abstract: The sliding member according to the present invention includes: a base material; and a sliding film that covers a surface of the base material and constitutes a sliding surface, and is used under a wet condition where lubricant oil exists. The sliding film according to the present invention is a laminated film that includes: an underlying layer formed on the surface of the base material; and an outermost layer formed at least on a part of the underlying layer. This outermost layer is characterized by including specific boron-containing amorphous carbon (specific B-DLC) that contains 4-50% B and 5-50% H when the outermost layer as a whole is 100 at %. This specific B-DLC itself wears away during the sliding to smooth the sliding surface, and an excellent low friction property is exhibited. The underlying layer of the specific B-DLC contributes to improvement in the wear resistance property of the sliding film.

Abstract: An object of the present invention is to realize low pressure loss and high purification performance in a constitution in which a primary catalyst component and co-catalyst component are loaded onto a ceramic support that allows catalyst components to be loaded directly. According to the present invention, a primary catalyst component in the form of a catalyst precious metal and a co-catalyst component in the form of an oxygen occluding component are loaded on the surface of a honeycomb-shaped ceramic support, including the inner surfaces of pores. As a result of the large loaded amount of co-catalyst component entering inside the pores, the loaded amount of co-catalyst component on the cell wall surfaces is reduced, thereby making it possible to inhibit increases in pressure loss. In addition, since the primary catalyst component and co-catalyst component are in close proximity to each other, catalyst performance is improved.
