A magnetic-inductive flow measuring device includes measuring electrodes, each having an end face including a planar annular edge region surrounding a center region, each annular edge region configured to seat against a sealing surface of an inner mold such that the center region of the end face does not contact the inner mold during the injection molding of a measuring tube body. A method for manufacturing the magnetic-inductive flow measuring device includes steps of providing and positioning an inner mold, an outer mold and two measuring electrodes, where each annular edge region of each measuring electrode seats against its corresponding sealing surface of the inner mold such that the center region of the measuring electrode protrudes into the corresponding recess of the inner mold without contacting the inner mold.
