Abstract: A resin-bonded body of a fuel injection apparatus includes a first resin material and a second resin material, which are bonded together and have different properties, respectively. The resin-bonded body has a fuel seal portion to limit leakage of fuel from a boundary surface between the first resin material and the second resin material to an outside. The fuel seal portion is formed in a portion of the boundary surface and is surface-modified to increase hydrophilicity of the fuel seal portion.

Abstract: A method of production of an ignition coil which provided with a core so as to form a mold release film which enables reduction of the adhesion with an epoxy resin comprising using a metal to form a rod-shaped center core, dipping the formed center core in a liquid UV curing resin, raising the center core from the liquid and shaking off the excess UV curing resin, irradiating the center core with UV rays to cause the UV curing resin which is deposited on the center core to cure and form an insulating film, attaching a first spool to the outside of the insulating film and winding a secondary coil over it, attaching a second spool to the outside of the secondary coil and winding a primary coil over it, inserting these into a case, then injecting an insulating material into the case to thereby produce an ignition coil.
