PURPOSE:To improve resolution by connecting plural superconductive quantum interference elements in series and connecting respective input coils in series. CONSTITUTION:When it is assumed that a voltage DELTAV is developed at a superconductive quantum interference element S1 by flowing a current I to an input coil 3A1, a voltage DELTAV is developed at respective elements 3A1, 3A2-3AN by flowing the current I to a set 3A of N series connection type input coils. Therefore, N.DELTAV is developed across all the elements Si and an output voltage which is N times as high as the signal current flowing through the coil 3A is obtained, so that the resolution is improved.
