PROBLEM TO BE SOLVED: To solve problems such that a primary coil is thermally expanded due to heating at a high temperature when insulation resin is hardened under a high temperature condition after a coil is housed in a case and filled with the insulation resin such as epoxy resin, and therefore, the primary coil is enlarged in an outer peripheral direction and deformed in a direction for loosening a coil, a lead-out position of the primary coil is displaced, so as to cause upward and downward inclination of a primary terminal fastened to the primary coil and a change of lead-out length due to displacement of the primary terminal in a lead-out direction.SOLUTION: A mold type transformer has: a primary coil; a case body in which a secondary coil is wound and housed, and in which insulation resin is injected; and a pair of primary terminals whose outer ends are introduced from primary terminal fitting and insertion holes provided on the case body and whose inner ends are fastened to a winding end of the primary coil in the case body. A terminal fitting and insertion part supporting the primary terminal and contacting the winding end of the primary coil to prevent displacement of the primary coil is provided on the terminal fitting and insertion hole on an inner side of the case body. |
