摘要： A flexible substrate (104) is wound around a magnetic core (102) to constitute an antenna coil (100). On the flexible substrate (104) formed are a receiver coil (106) including a first receiver coil portion (107a) and a second receiver coil portion (107b) which have opposite directions of winding, and a transmitter coil (108) including a first transmitter coil portion (109a) and a second transmitter coil portion (109b) which have opposite directions of winding. A region in which the receiver coil (106) is formed and a region in which the transmitter coil (108) is formed at least partially overlap each other when viewed in plan view, and non-coil-wound portions (110) are formed between the first coil portions (107a and 109a) and second coil portions (107b and 109b) in the coils (106 and 108).
