To provide a method for safely and profitably producing the silane compound.

This method for producing the silane compound comprises performing the first reduction of a silicon halide compound with sodium borohydride and/or the reaction product of the sodium borohydride with an aluminum chloride, and simultaneously performing the second reduction of a compound to be reduced, such as a carboxylic acid, olefin, a diene, an aldehyde, a ketone, a nitrile, an epoxide, an ester, and an acid chloride, with a borane and/or a diborane by-produced on the first reduction.
