<p>PROBLEM TO BE SOLVED: To provide a non-contact transformer wherein a transformer is placed on the bottom of a housing and a printed board is attached onto the transformer so that, even if an air core of the transformer is hollowed having caps on its both ends, the air core can be filled with resin without leaving air and no nonconformity such as deformation of the housing or the like occurs. SOLUTION: One cylinder end surface 3a of a primary transformer 3 is placed on the bottom surface 2a of a primary housing 2 opposite to a secondary housing 4. A terminal 12 is provided on the other cylinder end surface 3b of the primary transformer 3, and a printed board 7 is attached thereto. The primary transformer 3 is buried in a resin 6 that is applied into the primary housing 2. A penetrated passage 10 is provided between the printed board 7 and primary transformer 3 to communicate the air core 1 of the primary transformer 3 with the outside of thereof.</p> |
