摘要： A laminated balun transformer that achieves improved balance characteristics and prevents the occurrence of parasitic inductance has an impedance transformation ratio of one to four and outputs balanced signals generated from an unbalanced signal. The laminated balun transformer includes a magnetic substrate, a laminated body, and external electrodes. The laminated body includes a first transformer, a second transformer, and a non-magnetic body which completely covers the first and second transformers from the outside. The first and second transformers are arranged side by side in a direction substantially parallel to the magnetic substrate. A primary coil of the first transformer and a secondary coil of the second transformer are configured to be 180-degree rotationally symmetric with respect to a center line, while a secondary coil and a primary coil are also configured to be 180-degree rotationally symmetric with respect to the center line L.
