Natalya Zakharova's lawyer said she has 10 days to appeal the verdict.
Zakharova's efforts to regain custody of her 11-year-old child from her French ex-husband Patrick Ouary have met with little success so far, even though her case was brought to the attention of Russian President Vladimir Putin and his French counterpart, Jacques Chirac, in 2001.
Zakharova is allowed to visit her daughter once every three weeks, and only in the presence of a social worker.
She alleges that her appeal with the European Court of Human Rights a few years ago prompted French authorities to fabricate a criminal case against her, bringing charges of attempted arson of her former husband's house and of tarnishing France's international image by disclosing her story to the media.
