摘要

PPROBLEM TO BE SOLVED: To provide an irregular-surfaced structure with an increased surface area. PSOLUTION: The irregular-surfaced structure is composed of a base 20 and protrusions 30 formed on the principal plane thereof and has an increased surface area because each protrusion 30 has a groove 32 on the base. In one embodiment of the irregular-surfaced structure, the region confined by the surface of the base 20 and the surfaces of the protrusions 30 serves as a channel, and a catalyst 40 is supported on the principal plane of the base 20 and the surfaces of the protrusions 30, so that the amount of the catalyst 40 supported per unit volume can be increased.
