In the same verdict, the Paris criminal court also handed top division club Montpellier’s owner Mohed Altrad an 18-month suspended prison sentence, AFP said.
The court was not immediately available for comment.
Laporte was accused of undue influence in securing a role for his friend Altrad, whose construction company sponsors the France jersey. Both men denied any wrongdoing.
Le Parisien reported Laporte was found guilty of several offences including illegal taking of interest, influence peddling, corruption, and embezzlement.
He will be banned from holding any position in rugby for two years, the paper added.
Next year’s Rugby World Cup will be held in France from Sept 8 to Oct 28.
The verdict can still be appealed.
