A sealing apparatus is provided with a sealing block and inductors embedded in the sealing block. Each of the inductors is partially exposed above the surface of the sealing block and is provided with a first pressing portion for pressing the packaging material. The sealing apparatus also includes counter elements, each of which is disposed in opposing relation to the inductors so that packaging material can be squeezed between the counter elements and the inductors. In addition, a voltage applying device is provided for inductors and the counter elements are provided with a second pressing portion at a position corresponding to the portion of the packaging material that is nearer to a liquid food than to the sealing zone.
