Fuel injection valve

Abstract

A low-cost and compact fuel injection valve that requires a minimum number of man-hours for production and that allows repair of a flaw or a pinhole in an insulating coating is provided. The fuel injection valve has an electromagnetic coil using an insulated coil wire covered with an insulating coating and having a fusion bonding layer with self-fusing properties coated over the insulating coating. Therefore, it is possible to dispense with the use of a bobbin and hence possible to provide a low-cost and compact fuel injection valve that requires a reduced number of man-hours for production. Further, a flaw or a pinhole in the insulating coating is repaired by self-fusion, and thus insulation properties and waterproofness are improved. Accordingly, it is possible to prevent disconnection of the coil due to electrolytic corrosion.
