Disclosed is a method for producing a boric acid compound, by which a boric acid compound having excellent characteristics and reliability can be produced by a simple procedure at low cost. Specifically, a first compound that has a composition represented by MxByOz (wherein M represents at least one kind of atom selected from among Fe, Mn, Co and Ni, the valence N1 of M satisfies +2 = N1 = +4, and 0.8 = x/y = 1.2) and a second compound that contains at least one kind of atom A selected from among Li, Na and K are blended so that the atomic ratio among A, M and B (A:M:B) is a:b:1 (provided that 0 < a < 2 and 0.8 < b < 1.2). After mixing and pulverizing the blend of the first compound and the second compound, the resulting product is heated in an inert gas or a reducing gas, thereby producing a boric acid compound that has a composition represented by AaMbBOc (wherein the valence of M is equal to or less than N1, and c represents a number that is dependent on the numbers of a and b and the valence of M.) |
