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.
