An object of this technology is for one apparatus to effectively notify the other apparatus whether or not synchronization target clocks are correctly synchronized therebetween. A wireless apparatus includes a main control section, a wireless control section, and a clock synchronization management section. The main control section manages time using a first clock (synchronization target clock). The wireless control section manages time using a second clock (reference clock). The synchronization management section manages a clock synchronization state. The wireless control section notifies another wirelessly connected wireless apparatus of information regarding the clock synchronization state through transmission of a frame.
