Object: To provide a high performance scroll type fluid machine in which machining is facilitated, strength of central end portion of scroll wrap is high enough, volume of the innermost compression chamber becomes zero and yet compression efficiency does not lower. Solving means: A central end portion profile of spiral wrap of each scroll (1, 2) is formed in a step- like shape having at least two steps (1A, 1B and 2A, 2B), the central end portion profile of each said step is made in a complete engagement profile and thickness of said step-like spiral wrap is made thinner at the upper step leaving an end plate.
