A fuel filler port comprising:

• a fuel filler port main body made of resin, formed in a tubular shape and having an interlock part on an outer circumferential surface thereof;
• an inlet metal fitting at least having an outer tube part, the outer tube part being formed in a tubular shape, positioned and disposed in the fuel filler port main body, and disposed to face the outer circumferential surface of the fuel filler port main body in a radial direction;
• and
• an earth metal fitting formed in a plate shape and interlocked with the interlock part of the fuel filler port main body,
• wherein the earth metal fitting comprises
• a tip bent part disposed between the outer circumferential surface of the fuel filler port main body and an inner circumferential surface of the outer tube part of the inlet metal fitting in the radial direction and disposed in a state of having a biasing force in the radial direction with respect to the inner circumferential surface of the outer tube part of the inlet metal fitting.
