In an electromagnetic flowmeter, a magnetic field is generated in a direction perpendicular to measured fluid passing through a measurement tube, and electromotive force generated according to a flow rate of the fluid intersecting the magnetic field is detected by a pair of electrodes opposed on a diameter of the measurement tube. The electromagnetic flowmeter includes one pair of electrodes diametrically opposed on the measurement tube, first magnetic circuit forming members mounted on outer peripheries of both ends of the measurement tube, second magnetic circuit forming members for mutually connecting the first magnetic circuit forming members and pressing and supporting coils on the measurement tube, and a case made of non-magnetic material, for covering the measurement tube, the electrodes and the coils.
