<p>PURPOSE:To easily produce the subject transformer at low cost in high productivity by laminating a thermoplastic resin sheet on a ferrite core provided with a short ring etc., followed by hot contact bonding. CONSTITUTION:A nontacky thermoplastic resin sheet 8 as adhesive engaging material with a melt index of pref. 0.05-20 is put on a ferrite core 1 provided with a short ring 2 or a coil, and the sheet 8 is pref. laminated with another nontacky sheet 9 followed by hot contact bonding, thus obtaining the objective rotary transformer.</p> |
