Patent number: 7714687Abstract: In a transformer including a coil part having a first bobbin to which a coil is mounted, a second bobbin to be fitted to the first bobbin combined to each other, the coil part being sandwiched between magnetic cores from above and below, the first bobbin includes at least one lead drawing through holes on a periphery on the inner peripheral side of a coil mounting surface, and at least one of coil-drawn-leads of the coil is drawn through the lead drawing through hole. With this transformer, coming out of the coil-drawn-lead, displacement, and erroneous wiring are prevented, and hence the inserting capability of the coil is improved. Therefore, the workability is remarkably improved, and hence a product which is low in price can be provided.Type: GrantFiled: February 28, 2005Date of Patent: May 11, 2010Assignee: Panasonic CorporationInventors: Tomio Marui, Koji Nakashima, Toshiyuki Nakata
