Abstract: A method and an apparatus for producing sodium borohydride that have excellent energy efficiency and production efficiency are provided. Using a production apparatus 20 comprising: a cylindrical reaction container 21; a cylindrical reaction portion 22 which is rotatably held in this reaction container 21 and in which sodium metaborate that is a raw material 1 and granular aluminum are housed together with a grinding medium 2; and a hydrogen introduction portion 23 for introducing hydrogen gas into the reaction portion 22 directly or via the reaction container 21, the sodium metaborate and the granular aluminum are reacted under a hydrogen atmosphere, while being rolled and ground with the grinding medium, to obtain sodium borohydride.
