Police sources told Reuters the man was a "radicalised Muslim" who was on a security watch list.
A French Interior Ministry spokesman said no explosives were found on his body.
No-one else was injured in the incident.
ITV News reports that he attacked a patrol of three soldiers, wrestling a female soldier to the floor and trying to take her weapon.
The French Interior Ministry confirmed that two other patrolmen shot at the man "to protect her" and the public.
Both terminals at Paris Orly were evacuated and all flights suspended, with some diverted to Charles de Gaulle, the Guardian reports.
