Provided is a pipe buried structure with improved adhesiveness between a pipe forming a flow path and a metal member, and a method of manufacturing the same. A pipe buried structure 1 is provided with a pipe 10 made of metal or alloy, an outer periphery on a cross section of which has a flattened shape obtained by curving both ends in a longitudinal direction, a base material 11 made of metal or alloy on which a concave portion 11a is formed, the portion including an inner wall which an outer peripheral portion 10c in the longitudinal direction abuts and to which the pipe 10 is fitted, and a deposition layer 12 formed by accelerating powder made of metal or alloy together with gas and spraying the same in a solid phase state on surfaces of the pipe 10 and the base material 11, thereby depositing the powder in a state in which the pipe 10 is fitted to the concave portion 11a, wherein a ratio h/R between a protruding amount h by which the pipe 10 protrudes from the surface of the base material 11 and a curvature R at ends 10a and 10b is not smaller than 0.25 and not larger than 0.5. |
