Le lemme fondamental m\'etaplectique de Jacquet et Mao en \'egales   caract\'eristiques
  We prove in the case of equal characteristic a fundamental lemma conjectured by Jacquet and Mao for the metaplectic group. We use the arguments of Bao Ch\^au Ng\^o for Jacquet-Ye's fundamental lemma and a geometric study of the metaplectic extension.
