A multi-band antenna includes one or more a loop portions substantially defining operation in frequency ranges covering between approximately 800 MegaHertz and approximately 1. According to the present invention, the 3-D pointing device may not transmit an operation signal if the 3-D pointing device is not manipulated during a set time. At least one of the inorganic fiber and whisker contained in the honeycomb structure is oriented mainly in a first direction.
