Claim:
1. A dry etching material for forming a resist layer on an etching layer, the resist layer comprising: a heat-reactive resist material for dry etching and forming the resist layer on the etching layer, and the resist layer having opening portions associated with a concavo-convex structure, a pattern pitch P of a fine pattern of the concavo-convex structure ranges from 1 nm to 10 μm, a pattern depth H of the fine pattern ranges from 1 nm to 10 μm, a pattern cross-sectional shape of the fine pattern is a trapezoid, triangle or a mixed shape thereof, wherein the heat-reactive resist material contains: an oxide of Cr; and an additive, the oxide of Cr is comprised of CrO the additive is formed by containing at least one material selected from materials that do not form respective compounds with the CrO the additive consists of SiO 2 having a content of 10 mol % or more and 15 mol % or less, the pattern cross-sectional shape satisfies Equation (1) T T B
