Wales stand five points ahead of France at half time, despite missing two penalties.
Fans first observed a minute’s silence to remember former Wales captain and Lions star Mervyn Davies, who died this week at the age of 65.
France put the first points on the board with a penalty by Dimitri Yachvili.
But a superb try by Alex Cuthbert at 21 minutes, converted by Leigh Halfpenny, put Wales firmly in the lead.
Another penalty by Halfpenny added three to the difference.
Wales footballer Robert Earnshaw has sent his best wishes to fellow Welsh sportsmen.
