PROBLEM TO BE SOLVED: To realize a low-cost and high-reliabile electronic apparatus by removing defects or restrictions in a conventional data transmission system by solving various problems in the case of transferring a large amount of data at high speed by radio between circuit blocks in an electronic apparatus, particularly by solving problems of interference exclusion and antenna size when there is a strong electromagnetic wave transmission source that is an original purpose of the apparatus, inside said apparatus. SOLUTION: In an electronic apparatus which is equipped with a first transmission unit for performing a first communication by an electromagnetic wave; a second transmission unit for performing a second communication by an electromagnetic wave; and a reception unit for receiving a signal transmitted from the second transmission unit, the electronic apparatus is comprised of an antenna configured of a radiator having a size which is smaller than 1/(2π) of a wavelength of a use electronic wave, which is connected to at least the second transmission unit and the reception unit.
