A shield layer (71) is provided with an opening (71a) through which a magnetic flux generated by means of a power supply coil of an antenna (80) passes. Since the antenna (80) is small compared with the shield layer (71), the opening (71a) is extremely small compared with the size of the shield layer (71). Consequently, electromagnetic waves as noise, said electromagnetic waves being to be transmitted from the inside to the outside of a computer through an opening formed in an upper surface cover, can be sufficiently blocked. Furthermore, at the time of performing communication, the antenna (80) and the shield layer (71) are electromagnetically coupled to each other, and the shield layer (71) functions as an antenna. Consequently, communication can be excellently performed with a subject with which the communication is to be performed. |
