Iran sentenced Franco-Iranian academic Fariba Adelkhah to six years in prison on national security charges, according to his lawyer.
Saeid Dehghan told the Reuters News Agency on Saturday that he would appeal against the verdict.
"Branch 15 of the Tehran Revolutionary Court sentenced her to five years in prison for assembling and conspiring against Iran's national security. She was also sentenced to one year in prison for propaganda against the Islamic Republic," he said.
Iran dropped the espionage charges against Adelkhah, but she remained in prison for other security-related charges, Dehghan said in March.
Later on Saturday, France condemned Adelkhah's conviction in Iran and demanded his immediate release.
"This sentence is not based on any element or serious fact and is therefore a political decision," the French Foreign Ministry said in a statement. "We are asking the Iranian authorities to release Ms. Adelkhah immediately."
Iran had previously rejected France's request to release Adelkhah, a 60-year-old anthropologist, who has been in detention since June 2019, saying the demand is considered interference in his internal affairs.
Tehran does not recognize dual nationality.
In March, Iran released Adelkhah's partner, French academic Roland Marchal, who was arrested along with her.
Marchal was released after France released Iranian engineer Jalal Ruhollahnejad, who was detained for alleged violations of U.S. sanctions against Tehran.
A French court in May 2019 approved the extradition of Ruhollahnejad to the U.S. to face charges of attempting to illegally import U.S. technology for military purposes on behalf of an Iranian company that, according to U.S. officials, was linked to the Guard's elite.
