Abstract
Disclosed is an NFC antenna that facilitates a touch operation of a portable electronic instrument. An NFC antenna includes insulating substrates and an antenna coil having a front surface pattern and a back surface pattern formed on antenna surfaces that are present on the same planes. The insulating substrates are molded into an L shape together with a magnetic sheet sandwiched therebetween. The antenna coil is also arranged in the L shape in a similar manner. When the NFC antenna is arranged at a corner of a smart phone, a coil opening faces to a position of a touch corner. NFC can be started in a short time by a touch operation using the touch corner.
