The present invention provides an electromagnetic flowmeter using lighter coil than an existing coil, and having a magnetic field of a same size using a coil in a printable electronic technology. According to the present invention, the electromagnetic flowmeter comprises: a first FPCB coil made of a soft material which has a first input terminal located on an outer side, a first output terminal located on an inner side, a first coil pattern generating an electromagnetic field from the first input terminal to the first output terminal, and a first core formed on a center of the first coil pattern; a second FPCB coil formed of the soft material, which has a second input terminal located on an inner side, a second output terminal located on an outer side, a second coil pattern generating the electromagnetic field from the second input terminal to the second output terminal, and a second core formed on the center of the second coil pattern; and an electromagnet laminating the first FPCB coil and the second FPCB coil such that the first FPCB coil and the second FPCB coil are electrically connected to each other, wherein the first core and the second core formed on a central axis of the first FPCB coil and the second FPCB coil respectively are installed to be matched with each other. |
