Abstract: The present invention relates to a diagnostic apparatus and a method for manufacturing the same. The diagnostic apparatus according to an embodiment of the present invention comprises a base plate including an insulator, and one or more electrodes formed by penetrating through the base plate and causing a fluid located on a surface to be moved based on an applied voltage, in which the base plate is formed by injecting the insulator into a first space of a mold by a first injection gate, and the electrode is formed by injecting conductive plastic into a second space of the mold by a second injection gate distinct from the first injection gate.
