It is possible to mitigate a load of POI search and provide non-overlapping POI information to a user. Included are: a communication unit which acquires a POI search request signal to request search of the POI from a POI information providing device; a memory unit which stores user utterance information storing a genre when voice information of user utterance specifying the genre of the POI is included in the POI search request signal; and a control unit which searches a POI of a genre specified by voice information when the voice information of user utterance specifying the genre of the POI is included in the POI search request signal, determines whether a predetermined POI search condition is satisfied when the voice information is not included in the POI search request signal, searches a POI of a genre specified by the user utterance information when the predetermined POI search condition is satisfied, and generates notification POI information including voice information relating to the searched POI.
