<p>PROBLEM TO BE SOLVED: To provide a coil device that is suitable for downsizing and improves reliability and manufacture efficiency.SOLUTION: A coil device 10 is changed from low pressure to high pressure in a winding shaft direction. The coil device 10 includes: a bobbin 20 including a rod-like core, a hollow cylinder accommodating the core and a plurality of flanges protruding from the hollow cylinder in an outer diameter direction; a secondary coil 40 which is wound separately around a plurality of secondary coil grooves which are formed on an outer peripheral surface of the hollow cylinder while being held between the flanges; a primary coil 30 which is wound separately around a plurality of primary coil grooves which are formed on the outer peripheral surface of the hollow cylinder while being held between the flanges between the secondary coil grooves; a low-pressure side terminal 50 provided in any flange and connected to the primary coil and the secondary coil; a primary high-pressure side terminal 60 which is provided in any flange and to which a primary high-pressure side end portion of the primary coil is connected; and a secondary high-pressure side terminal 70 which is provided in any flange and to which a secondary high-pressure side end portion of the secondary coil is connected.</p> |
