To provide a card enclosure simulation server that completely satisfies a request of an ordering party at a design stage before manufacturing of a test result object.

A card enclosure simulation server comprises means for: storing design data of respective layers of a card, a card mount and an enclosure; generating an image of a card face on the basis of the design data of the card layer and causing a terminal to display the image generated; generating an image of the card mount on the basis of the design data of the card mount layer and causing the terminal to display the image generated; superimposing the image of the card face on the image of the card mount, generating an image in which the card is attached to the card mount and causing the terminal to display the image generated; generating an image of an envelope on the basis of the design data of the enclosure layer and causing the terminal to display the image generated; and generating an image of the card mount in a folded state on the basis of the design data of the card mount layer, superimposing the image of the card mount in the folded state on the image of the envelope, generating an image in which the card mount is folded and enclosed in the envelope and causing the terminal to display the image generated.
