PROBLEM TO BE SOLVED: To provide a smaller noncontact transmitter by constituting a ferrite core, a coil, and an electric circuit board integrally so as to materialize downsizing of a transmission part and reduction of number of parts enough. SOLUTION: This is a noncontact type of transmitter which includes coils 1 and 2, and 6 and 7 opposed to each other across space. Its one hand serves as input or transmission side, and the other hand serves as output or reception side, and transmits signals or power, making use of the electromagnetic inductive active generated between opposed coils 1 and 2, and 6 and 7, the coils 1 and 2, and 6 and 7 are arranged at the ferrite cores 21 and 31 as the base material of a printed circuit board. |
