Disclosed is a positive radiation-sensitive resist composition comprising polymer(s) of the following general formula (1) and a radiation-sensitive agent. <IMAGE> (1) <IMAGE> Ra, Rb, Rc and Rd each are independently a hydrogen atom, a hydroxyl group, a halogen atom, an alkyl group, an alkoxy group, an alkenyl group, an aryl group, an aralkyl group, an alkoxycarbonyl group, an arylcarbonyl group, an acyloxy group, an acyl group, or a cycloalkyl group; k is an integer of from 1 to 30; (1+n) is an integer of from 1 to 100; m is an integer of from 1 to 50; p1, p2 and p3 each are an integer of from 1 to 3; q1 is an integer of from 1 to 4. The resist composition has high resolution to give resist patterns with good profiles and has high heat resistance and good storage stability.
