<p>PROBLEM TO BE SOLVED: To provide an isolation transformer which can reliably perform signal and power transmission by restricting an interval between primary and secondary cores to be a prescribed value. SOLUTION: In an isolation transformer 10, wherein primary and secondary cores 11 and 12 each having a core of made of synthetic resin containing soft magnetic material and a coil obtained by winding an electric wire are positioned as opposed to each other to transmit power or an electrical signal on a noncontact basis between the primary and secondary cores 11 and 12, stopper members 18 and 19 are fixed at either of the ends to those associated of the both cores to restrict the displacement of the other cores, so as not to prevent both cores from being spaced by a constant distance or more.</p> |
