A resist composition comprising a hypervalent iodine compound, a carboxylic acid derivative, and a solvent is provided. When processed by photolithography using high-energy radiation, the resist composition exhibits a high sensitivity and improved maximum resolution. The non-chemically-amplified resist composition exhibits a high sensitivity and improved maximum resolution when processed by photolithography using high-energy radiation, typically EB and EUV lithography.

A radiation-sensitive composition includes: an onium salt compound represented by formula (1); a polymer including a structural unit (I) which includes an acid-dissociable group; and a solvent. W is a cyclic structure having 3 to 40 ring members formed together with the two carbon atoms; a formula between the two carbon atoms below represents a single bond or a double bond, , A is one of groups represented by formulae (A-1) to (A-7); R.sup.1 is a monovalent organic group having 1 to 20 carbon atoms, a cyano group, a nitro group, a carboxy group, a hydroxy group, an amino group, a halogen atom, or a thiol group, when there are a plurality of R.sup.1s, the plurality of R.sup.1s are same as or different from each other; m.sub.1 is an integer of 0 to 4; and Z.sup.+ is a monovalent radiation-sensitive onium cation.
