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.
