Abstract: An inference device detects, with a detection section, an electrical characteristic between plural predetermined detection points on a vehicle seat provided with a soft material that is conductive and that exhibits a change in an electrical characteristic according to a change in pressure imparted. An inference section employs a learning model to infer a posture state of an occupant of the vehicle seat from the electrical characteristic of the vehicle seat. The electrical characteristic when pressure has been imparted to the vehicle seat and the posture state information indicating the posture state of the occupant when imparting pressure to the vehicle seat are employed as training data for a learning model trained so as to be input with the electrical characteristic and output the posture state information, and trained so as to be input with the electrical characteristic and output the posture state of the occupant corresponding to the input electrical characteristic.
