The present invention provides a radiation sensitive resin composition which comprises (A) a resin represented by a copolymer comprising recurring units represented by the general formulae (1) or (2) as shown below, and (B) a radiation sensitive acid-generator. The radiation sensitive resin composition has an excellent storage stability and the resist produced from the composition is a chemically amplifiable type sensitive to radiations represented by fartificial ultraviolet rays. The resist has a high transparency to radiations and it is excellent in basic physical properties for resist such as durability to dry etching, sensitivity, resolution, and pattern configuration:
