From the Swedish Transport Agency:
Am I allowed to drive in Sweden with a foreign driving licence?
Yes, provided you have your driving licence with you when driving. Either your driving licence must have a photograph of yourself on it or you must, when driving, also have a valid ID document with you containing a photo. If your driving licence has not been issued in English, German or French, the police may also require you to have with you a certified translation of your driving licence. An international driving licence is a certified translation that can be used for this purpose.
Since your license has been issued in French, it appears that you do not need an IDP or any other certified translation.
