<p>PURPOSE: To cut down the number of the parts of a feedthrough current transformer and reduce its size, by providing a shield member fastened to both its end surfaces via first screws, and by fastening easily it to a grounded container via second screws. CONSTITUTION: First and second screws 15a, 16 are connected by a connection wire 17, and a secondary winding 3, the first and second screws 15a, 15b, 16 and the connection wire 17 are molded in a body to configure a feedthrough current transformer 18. First and third members 21, 23 constituting a shield member 24 are fastened to both the end surfaces of the feedthrough current transformer 18 via the first and second screws 15a, 15b, 16. Also, the feedthrough current transformer 18 molded in a body is fastened to an attachment frame 19 formed in one portion of a grounded container 1 via the second screws 16.
