FLUID SUPPLY PIPE

A fuel supply pipe (43) is constituted of a fixed fuel supply pipe (43b) made of a metal such as stainless steel and connection fuel supply pipes (43a, 43c) made of, e.g., resin. The volume resistivities of the connection fuel supply pipes (43a, 43c) range from 10 to 10 OMEGA .cm. Therefore, the electrification of fuel in flowing through the fuel supply pipes (43a, 43c) can be suppressed. Since the electricity accumulated in the supply pipes (43a, 43c) is not discharged sharply, the supply pipe (43a) is prevented from causing spark discharge. The supply pipes (43a, 43c) each may have a multilayer structure of which the innermost layer has a volume resistivity ranging from 10 to 10 OMEGA .cm and of which the outermost layer has a volume resistivity of 10 OMEGA .cm or more.
