PROBLEM TO BE SOLVED: To provide a magnetic information transmission system capable of transmitting a large amount of information and transmitting the information stably for a long period of time as compaired to the case that an information transmission means is formed of a block having a plurality of projecting parts on its surface, and capable of surely transmitting the information without being affected by surrounding equipment, weather or the like as compaired to the case that the information transmission means uses electromagnetic waves. SOLUTION: The magnetic information transmission system is constituted of: a speech information output means 15 for outputting an electric signal according to speech information; a magnetic field generation means 5 for generating a magnetic field with intensity according to the electric signal from the speech information output means 15; speech conversion means 23/29 for converting the magnetic fields from the magnetic field generation means 5 into speech signals and speech output means 32/35 for performing speech outputs of the speech signals from the speech conversion means 23/29.
