Scroll fluid machine

A scroll fluid machine includes fixed and orbiting scrolls which form a compression chamber; a land which divides the compression chamber into first-stage and second-stage compression chambers; a wrap groove formed in a spiral shape along a tip of a fixed wrap of the fixed scroll; an intermediate groove formed in the land; a seal member; and an intermediate seal member. The land includes a front-stage outlet communicating with the front-stage compression chamber and a rear-stage inlet communicating with the rear-stage compression chamber. The wrap groove includes an outer peripheral wrap groove adjacent to the land on a radially outward side and an inner peripheral wrap groove adjacent to the land on a radially inward side. The intermediate groove is in communication with the outer and inner peripheral wrap grooves. The seal member is fitted in the wrap groove except the outer and inner wrap grooves. The intermediate seal member includes an outer peripheral seal portion fitted in the outer peripheral wrap gro
