The pipe structure according to the present invention includes: a fiber-reinforced plastic pipe 5; moisture-proof foils 11, 12 which individually cover an outer circumferential surface of the pipe 5 and an inner circumferential surface thereof; and an intermediate part 4 which is made of metal and fitted to an end of the pipe 5, wherein end portions of the moisture-proof foils 11, 12 are tightly sandwiched between the pipe 5 and the intermediate part 4. This configuration reliably prevents an FRP pipe from absorbing moisture, and thus, prevents the FRP pipe from shrinking due to moisture exhaustion in outer space, whereby it is possible to obtain the pipe structure having excellent dimensional stability.
