Disclosed are pyrazole-1-carboxylate derivatives of the general formula (1), (wherein symbols are as defined in the specification), a process for the production thereof and processes for producing herbicidally active 3-aryloxypyrazole-1-carboxamide derivatives from the above compound and an intermediate therefor. According to this invention, there can be industrially advantageously produced 3-aryloxypyrazole-1-carboxamide derivatives that does not cause chemical damage on crops but exhibits excellent herbicidal activity against weeds that impair the growth of such crops.
