To provide a pipe embedded structure that improves adhesive properties between a pipe that forms a passage and a metal member, and a method of manufacturing the pipe embedded structure. A pipe embedded structure 1 includes a pipe 10, a base material 11, and a deposited layer 12. The pipe 10 is made of a metal or an alloy, and has a periphery that forms a circular shape in a transverse section. The base material 11 is made of a metal or an alloy, in which a recessed portion 11a is formed. The recessed portion 11a allows the pipe 10 to be fitted therein, and has an inner wall on which a part of the periphery abuts, and a ratio h/R of a protruding amount h by which the pipe 10 protrudes from the upper surface 11b and a curvature R of the periphery is not smaller than 0.3 and not greater than 0.7. The deposited layer 12 is formed such that powder formed of a metal or an alloy is accelerated together with a gas in a state where the pipe 10 is fitted into the recessed portion 11a, and the powder is sprayed and deposited on surfaces of the pipe 10 and the base material 11 while remaining in a solid phase state. |
