Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a photoresist composition using an acid as a catalyst, capable of forming an image with radiation of 193 nm and capable of forming a photoresist structure having high resolution and high etching resistance by development. SOLUTION: The photoresist composition comprises a combination of a cyclic olefin polymer, a photosensitive acid-generating agent and a substantially transparent bulky hydrophobic additive. The cyclic olefin polymer contains a cyclic olefin unit having a polar functional group which promotes dissolution in an aqueous alkali solution and the cyclic olefin unit having an acid-labile group which inhibits the dissolution in the aqueous alkali solution. The hydrophobic additive is selected from the group comprising a saturated steroid compound, a non-steroid cycloaliphatic compound and a non-steroid polycycloaliphatic compound having an acid-labile bond.
