Wales slipped to defeat in their opening game in the triangular Autumn international series against France.
Wales scored an early try through David James to lead 6-0 as France missed a number of early chances.
However, the home side ran in three tries in nine minutes to lead 18-6 at half-time.
Gil Dudson received a yellow card after 50 minutes, reducing Wales to 12 men and handing France a penalty.
The series continues next Saturday when Wales host England.
