A question extraction unit extracts predetermined question elements such as "operation', "state', "question', etc. from question text transmitted from a questioner by electronic mail, etc. A case retrieval unit searches a question and answering case accumulation unit using a question element extracted by the question extraction unit as a retrieval key, and outputs a question case containing a matching question element to a answer presentation unit. The answer presentation unit reads an answer case corresponding to the retrieved question case from a question and answering case accumulation unit, and presents it to the questioner. Thus, the questioner can be provided with a desired answer.
