A Paris court found 29-year-old Hamza Mandhouj guilty of criminal conspiracy with terrorist aims and abduction of a minor and ordered that he must serve a minimum of half his sentence.
Denouncing the "appalling blackmail" he exercised on the child's mother, Meriam Rhaiem, the prosecution described the case as "a marital dispute overlaid by a wish to take part in armed jihad".
On 14 October, as divorce proceedings were going through, Mandhouj collected his daughter, Aissa, from his parents-in-law and never took her back.
He left for Turkey, going on to Syria in December to join his brother, Mohamed Ali, who was already working with Oumar Diaby, a recruiter for the Al-Nusra Front Islamist group.
Compensation for kidnapping
Mandhouj denied wanting to join a terrorist group but the prosecution claimed he gave logistical support to recruits and encouraged minors to come to Syria.
He was caught when his ex-wife, whom he phoned regularly to try to persuade her to join him, arranged a meeting in a hotel in Turkey near the Syrian border so that he could hand over Assia.
Mandhouj was ordered to pay 60,000 euros in compensation for the abduction.
Nearly 300 French jihadis dead
According to the French government, 1,700 French citizens have gone to the area during that period.
Figures brought up to date on Tuesday evening showed 256 adults and 78 minors had returned.
