A chip for analyzing fluid being moved without an outside power source is disclosed. A chip for analyzing fluid being moved without an outside power source according to the present invention comprises: a pre-treatment portion into which a target-being analyzed substance is injected and received; a channel portion through which the fluid received in the pre-treatment portion is moved and in which specific reaction of the fluid such as an antigen-antibody reaction is conducted; and a washing portion into which the fluid passing through the channel portion is received wherein the pre-treatment portion includes: a specimen injection portion into which the fluid is injected; a first buffer portion having a step difference with respect to the specimen injection portion for the fluid to be firstly received; and at least one specimen leading guide which is provided between the specimen injection portion and the first buffer portion and destroys surface tension of the fluid flow moving from the specimen injection portion to the first buffer portion side and thus stabilizes flow surface of the fluid. According to the present invention, a moving pattern of the fluid passing through a channel portion is formed evenly and thus bubble creation is decreased and reproducibility thereof is ensured and further a signal detection from a target-being analyzed substance is performed easily.
