A prefabricated channel buried in a concrete structure is provided to remove a need of additional fixing means, to effectively resist to the drawing force, and to prevent slopes formed on both sides of a channel body from being injured. A prefabricated channel(100) buried in a concrete structure comprises a bolt(40) combined with a bracket supporting an object; a body(20) installed with the bolt inside, protruded/inclined inward on the upper end of both sides to prevent the bolt from being separated, and formed with screw holes on the lower surface at regular intervals; a supporting member(30) formed with a screw thread on the outer peripheral surface to be engaged with a screw thread of the screw hole to be combined with the body and to support the body to place the upper end of the body to the same height with the upper surface of the concrete structure; and an auxiliary nut(35) installed at the supporting member to resist to the drawing force. A predetermined space is formed between a head unit(41) of the bolt and the lower surface of the body, and the supporting member is adjusted of inserted length into the screw hole to regulate height of the body correspondingly to the thickness of the concrete structure.
