Claim:
1. A noncontact connector system comprising: a first noncontact connector apparatus including a transmitter coil; and a second noncontact connector apparatus including the receiver that that is provided to be adjacent, so as to be electromagnetically coupled, to the transmitter coil, wherein the transmitter coil is configured to include a winding wound on a first plane, the first noncontact connector apparatus comprises: a first magnetic body provided between the first plane and a second plane which is opposed to be adjacent to the first plane and on which the receiver coil is provided, the first magnetic body being provided to be adjacent, so as to be electromagnetically coupled, to the transmitter coil and to cover at least one part of a region in which at least the winding of the transmitter coil exists, wherein the receiver coil is configured to include a winding wound on the second plane, the first magnetic body is further positioned to be adjacent to the receiver coil so to be electromagnetically coupled to the receiver coil and to cover at least one part of a region in which at least the winding of the receiver coil exists between the first plane and the second plane, thereby increasing the self-inductance of the receiver coil by positioning the first magnetic body to be adjacent to the receiver coil, a coupling coefficient between the transmitter coil and the receiver coil is set to be decreased by increasing the self-inductance of each of the transmitter coil and the receiver coil so that a frequency characteristic of transmission efficiency from the transmitter coil to the receiver coil changes from a double-peaked narrow-band characteristic to a single-peaked wide-band characteristic, and a center frequency of the double-peaked narrow-band characteristic is lower than a center frequency of the single-peaked wide-band characteristic.
