One of a pair of a fixed scroll and an orbiting scroll is the scroll including a step portion provided only at a predetermined position along a spiral direction on a blade bottom surface of a spiral wrap, and the other one of the scrolls is the scroll including a step portion provided only at a predetermined position along a spiral direction on a blade tip surface of a spiral wrap. A blade bottom surface of an end plate of the fixed scroll is set as a reference surface for setting a chip gap between both the scrolls. When a wrap height of the spiral wrap of the orbiting scroll is represented by (L) (Lo, Li) and a wrap height of the spiral wrap of the fixed scroll is represented by (lo, li), L (Lo, Li)>1 (lo, li) is satisfied.
