A biosensor electrode device and a method for fabricating the same are disclosed. The biosensor electrode device comprises a conductive substrate； at least one conductive spring, at least one probe, and an encapsulation member. Two ends of the conductive spring respectively connect with the conductive substrate and the probe. The probe moves close to or far away from the substrate through the elastic deformation of the conductive spring. The encapsulation member wraps the conductive substrate, the conductive springs and the probes but reveals a portion of each probe. The revealed probes contact skin of a testee for biomedical measurement. The device and method of the present invention can reduce the cost in mass-production. The biosensor electrode device will be a mainstream instrument in biomedical measurement.
