| 1. A cap for fuel tank, wherein the cap comprises an electrically conductive resin composition of a polyamide type, the electrically
conductive resin composition comprising the following components compounded:
a polyamide resin (A) forming a continuous phase,
electrically conductive carbon black (B), wherein not less than 80% by mass of the electrically conductive carbon black (B)
is dispersed in the continuous phase of the polyamide resin,
particles of an ethylene-α-olefin copolymer (C) having a reactive functional group which is able to react with a terminal
group of the polyamide resin and/or an amide group of the main chain of the polyamide resin, wherein the particles of the
ethylene-α-olefin copolymer (C) have an average particle diameter of not more than 2 μm and are dispersed in the continuous
phase of the polyamide resin (A), and
a high-density polyethylene resin (D).
