A behavior pattern storing unit stores stay point information for a plurality of stay points including a stay point of a first behavior base type corresponding to a first behavior type and a stay point of a second behavior base type corresponding to a second behavior type, a behavior characteristic extraction unit extracts days on which a stay at a stay point of the first behavior base type was performed as a day regarding the first behavior type by referring the stay point information, calculates, if a stay at an other stay point different from the stay points of the first and the second behavior base type was performed on days regarding the first behavior type, a stay frequency at the stay point of the first behavior base type during the same time zone as the stay at the other stay point, for the days regarding the first behavior type.
