A display unit (1203) scrollably displays product information obtained from a server. An estimation unit (1204) estimates whether a user has read notice information included in the product information. If it is estimated that the user has read the notice information, then when the user has operated an offer object included in the product information, a notification unit (1205) notifies an electronic shopping mall server (10) of the user's offer of buying the product indicated by the product information. In contrast, if it is estimated that the user has not yet read the notice information, the display unit (1203) displays a first object superimposed on the product information. Then if the user operates the first object, the display unit (1203) scrolls the product information so as to display the notice information. Thereafter, if it is estimated that the user has read the notice information, then the display unit (1203) displays a second object superimposed on the product information, and if the user operates the second object, the display unit (1203) scrolls the product information so as to display the offer object. |
