Abstract

Official abstract text for this publication.

A base is metal, ceramic, or a complex combining thereof, and has thereon multiple concave-convex patterns that are provided at one or more pitches equal to or less than 2 μm, and a surface part 1a of the base 1 is porous.

First claim

Opening claim text (preview).

What is claimed is: 1. A thermophoto conversion element comprising: a base comprising a metal, ceramic, or a combination thereof, and has thereon multiple patterns that are provided at one or more pitches equal to or less than 2 μm, each of the multiple patterns comprising a recess and a protrusion, wherein a surface part of the base is porous. 2. The thermophoto conversion element according to claim 1 , wherein the base comprises a plurality of cavities. 3. The thermophoto conversion element according to claim 1 , wherein the base has a three-layer structure comprising a first metallic layer, a dielectric layer, and a second metallic layer, the second metallic layer comprising the protrusions, and the recesses formed as gaps between the protrusions. 4. The thermophoto conversion element according to claim 1 , wherein a heat absorbing member is arranged on a surface of the base that is opposed to a surface on which the multiple patterns are provided. 5. The thermophoto conversion element according to claim 4 , wherein the base and the heat absorbing member are attached by an adhesion layer. 6. The thermophoto conversion element according to claim 1 , wherein a heat generating member is arranged on a surface of the base that is opposed to a surface on which the multiple patterns are provided. 7. The thermophoto conversion element according to claim 1 , wherein the multiple patterns are provided at two or more pitches.
