The invention discloses a method for preparing a medium bridge by using polyimide. The method comprises the following steps: coating a photoresist on a substrate and performing photo-etching to obtain a bridge deck; evaporating and stripping metal to form the bridge deck; coating the photoresist on the substrate and performing photo-etching to obtain a bridge pier; evaporating and stripping the metal to form the bridge pier; coating the polyimide on the substrate and solidifying the coated polyimide at a high temperature; etching residual polyimide by dry etching until the bridge pier is exposed; coating the photoresist on the polyimide and performing photo-etching to obtain a bridge pier lead; and evaporating and stripping the metal to form the bridge pier lead. The medium bridge prepared by the method takes the polyimide as a medium, and the bridge deck length of the medium bridge is not limited on the aspect of maximum span compared with a conventional air bridge, so the problem that the bridge deck in traditional air bridge process is easy to break is solved.
