The refined Demazure character formula was proved by \textit{M. Kashiwara} [Duke Math. J. 71, 839--858 (1993; Zbl 0794.17008)] and \textit{P. Littelmann} [J. Algebra 175, 65--87 (1995; Zbl 0831.17004)]. The aim of the paper under review is to give a purely combinatorial proof of this formula by using combinatorial properties of the crystals.
