Abstract: A scroll fluid machine includes: a fixed scroll 11 having a helical wrap 16; an orbiting scroll 12 having a helical wrap 21; a drive shaft 13 that causes the orbiting scroll 12 to orbit relative to the fixed scroll 11; and a helical tip seal 29A inserted into a seal groove 28A of the wrap 21. The tip seal 29A has: a groove 36A that has an opening at a central portion of a sliding surface 30 in the seal width direction; and a communication groove 37A communicating between the inside of the groove 36A and a working chamber SH on the inner side in the wrap width direction. In groove 36A the differential pressure (PH-PL) is equal to or higher than 0.1 Mpa between the working chamber SH and a working chamber SL on the outer side in the wrap width direction.
