PROBLEM TO BE SOLVED: To constitute an electric apparatus of such a refrigerant current velocity as charging of cooling medium due to fluid charging phenomenon is suppressed to have no effect on the dielectric strength without widening the interval of planar coils in the electric apparatus, e.g. a shell type transformer or a reactor. SOLUTION: In the electric apparatus having refrigerant channels on the opposite sides of a planar coil and being cooled by flowing cooling medium through the refrigerant channels, an edge part shield 20 comprising a conductive member 21 having the inner edge side copying the outer edge part of the planar coil 11a and the rounded outer edge side, and an insulating member 22 of U-shaped cross-section applied to the side part and the outer edge part of the conductive member 21 and having a thickness not exceeding that of the planar coil 11a is disposed at the outer edge part of the planar coil 11a and the conductive member 21 is connected electrically with the planar coil 11a.
