PROBLEM TO BE SOLVED: To provide a composite film which is excellent in surface smoothness and workability, has less surface blemishes, is excellent in productivity, and is suitable for mold-releasing. SOLUTION: This polyphenylene sulfide composite film has the layers A and B which are made by using a polyphenylene sulfide, and the layer A is at least one of the surface layers, and the total thickness is from 30μm to 200μm. The layer A is a layer which contains a total being from 0.5 wt.% to 2.0 wt.% of a single particle or a mixed particle of which the thickness is from 2μm to 20μm, of which the average particle size is from 0.3μm to 1.5μm based on the whole layer. The layer B is a layer which contains a total being from 0 to 5.0 wt.% of a single particle or a mixed particle of which the average particle size is 5.0μm or lower based on the whole layer.
