A fuel tank has a superior outer appearance. A body and a bottom are aligned to each other in a vertical direction to form a sealed closed space for storing fuel between both members. The body is formed as a container having an opening in a downward direction. A connected end part is bent inward in a continuous manner from a lower end of its outer surface. The opening is covered from below with the bottom and its circumferential edge is overlapped on the connected end while its position is set and connected at its entire circumference by brazing.
