ANTENNA COIL AND ANTENNA UNIT

摘要

An antenna coil (100) is constituted by winding a flexible substrate (104) around a magnetic body core (102). A receiving coil (106) consisting of a first receiving coil portion (107a) and a second receiving coil portion (107b) of reversed winding direction, and a transmission coil (108) consisting of a first transmission coil portion (109a) and a second transmission coil portion (109b) of reversed winding direction are formed on the flexible substrate (104). The region for forming the receiving coil (106) and the region for forming the transmission coil (108) are overlapping at least partially in the plan view, and the portions between the first coil portions (107a, 109a) and the second coil portions (107b, 109b) in each of the coils (106, 108) are portions (110) where a coil is not wound.
