To reduce power consumption.

An initiator prescribed by NFCIP (Near Field Communication Interface and Protocol)-1 transmits attribute information indicating communication ability of itself as well as receives attribute information indicating communication ability of a target from the target. When the received attribute information indicates that the target has communication functions in a power saving mode, the initiator reduces power of an electromagnetic wave to be outputted after receiving the attribute information. The present invention is applicable, for example, to an NFC communication device.
