Production process and intermediate of tetrazole compound

There are disclosed an industrially favorable process for producing a tetrazole compound of general formula (1): STR1 characterized in that a nitrile of general formula (2): is reacted with hydrazine or a salt thereof in the presence of a catalyst, followed by reaction with a nitrous acid compound of general formula (3): or a nitrile of general formula (2) is reacted with hydrogen sulfide, followed by reaction with an alkyl halide of general formula (4): with hydrazine or a salt thereof, and then with a nitrous acid compound of general formula (3); and an intermediate of general formula (5): which is useful for the production of the tetrazole compound (in which R1 to R6, A and J in the above formulas are as defined in the specification).
