An adaptive array antenna device (120) includes: a wireless transmission antenna unit (121) which wirelessly transmits content data to q partner device; a path information calculation unit (123) which calculates transmission path information for specifying radiation pattern with which the content data can be wirelessly transmitted to the partner device, before an instruction to transmit the content data to the partner device is issued; and a memory (124) in which the transmission path information calculated by the path information calculation unit (123) is stored. The wireless transmission antenna unit (121) starts transmitting the content data to the partner device using the radiation pattern specified by the transmission path information stored in the memory (124), when the instruction to transmit the content data to the partner device is issued.
