A data transmission device includes a display unit, a touch panel, a storage unit, a data transfer unit, a display control unit, and a control unit. When the display unit causes the display unit to display the selection of the transfer destination of the data, the display unit causes the display unit to display a list of the list indicating the name of the transfer destination stored in the storage unit. In a case where a plurality of transfer destinations displayed in the list are selected, the control unit causes the data transfer unit to transmit the data to the plurality of transfer destinations by using the one transfer method in the transfer method of the data to the transfer destination other than the one transfer destination when the touch panel receives a predetermined decision related to the transfer method of data from a user for one transfer method selected for the selected one transfer destination. According to the data transfer device, when data is transmitted to a plurality of transfer destinations, the operation load of the user can be reduced.
