The present invention provides an indazolesulfonylurea derivative represented by the general formula: ##STR1## �wherein R.sup.1 is a hydrogen atom or an alkyl group, etc., R.sup.2 and R.sup.3 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group, the formula --COR.sup.4 (wherein R.sup.4 represents an alkoxy group, etc.), an alkoxy group, a haloalkoxy group or a cyano group, etc., X is an oxygen atom or a sulfur atom, Y is a hydrogen atom or an alkyl group, etc., A and B are the same or different and represent a halogen atom, an alkoxy group or an alkyl group, etc., and Z represents a nitrogen atom or a methine group!, as well as a herbicide containing it as an active ingredient and an intermediate for its production. The compound of the present invention exhibits excellent herbicidal effects over a wide range from the preemergence stage to the growing stage of various weeds which are problematic in agricultural fields. Further, it is capable of controlling weeds germinating in paddy fields.
