The Bank of France has previously estimated that the euro zone's second-biggest economy grew 0.2 percent in the third quarter after stagnating in the first half of the year.
The central bank offered its latest take on French growth in its monthly business climate survey which showed sentiment in the industrial sector stood at 96 in October, unchanged from September.
The survey showed that sentiment in the services sector rose slightly to 94 from 93.
President Francois Hollande's Socialist government expects growth of just 0.4 percent this year before it accelerates to 1.0 percent next year, led by a hoped-for rebound in corporate investment.
