The present invention relates to a polypeptide probe for the diagnosis of HER2-positive breast cancer that specifically binds to HER2. When the polypeptide probe for HER2 detection, the composition for diagnosing breast cancer or the diagnostic kit of the present invention is used, HER2-positive breast cancer with poor prognosis can be diagnosed early. Also, in the case of the polypeptide probe for HER2 detection of the present invention, it is possible to provide a small molecule probe which is easier to manufacture than conventional antibodies, has high physical and chemical stability, and is easily injected into the body. |
