Provided is a communication apparatus, with which, while maintaining communication characteristics, a housing of an electronic apparatus can be reduced in size and thickness when the communication apparatus is assembled to the electronic apparatus. The communication apparatus is provided with: an antenna substrate (11) having an antenna coil (11a) formed thereon, said antenna coil to be inductively coupled with a reader writer (120); a magnetic sheet (13), which is disposed at a position superimposed on the antenna coil (11a) formed on the antenna substrate (11), and draws a magnetic field to the antenna coil (11a), said magnetic field having been transmitted from the reader writer (120); and a film-like protection member (15), which is laminated on surfaces other than the surface where the magnetic sheet (13) and the antenna coil (11a) are superimposed on each other, and which covers the whole end portions (13a, 13b) of the magnetic sheet (13). The antenna coil (11a) and the magnetic sheet (13) are superimposed on each other by having the magnetic sheet (13) inserted into a center portion (11c) of the antenna coil (11a) formed on the antenna substrate (11).
