A display (1203) displays product information acquired from a server in a scrollable manner. An estimator (1204) estimates whether or not a user has read warning information included in the product information. If it is estimated that the warning information has been read, and an order object included in the product information is operated by the user, a notifier (1205) notifies an electronic shopping mall server (10) of a purchase order by the user for the product related to the product information. The display (1203) displays a first object superimposed onto the product information while it is estimated that the warning information has not been read, and if the first object is operated by the user, the display (1203) scrolls the product information so that the warning information is displayed. The display (1203) displays a second object superimposed onto the product information after it is estimated that the warning information has been read, and if the second object is operated by the user, the display (1203) scrolls the product information so that the order object is displayed.
