To provide a reliable laminated balance transformer that can be miniaturized, and at the same time suppresses variation in electromagnetic coupling.

The laminated balance transformer has first to fourth coils (h) to (k) formed in the thickness direction of a laminate 11. The first and second coils (h) and (i) are formed oppositely. The third and fourth coils (j) and (k) are formed oppositely. One end of the first coil (h) is set to a signal input end, and is connected to one end of the fourth coil (k). The other of the first coil (h), one end of the second coil (i), one end of the third coil (j), and the other of the fourth coil (k) are grounded. The other of the second coil (i) is set to a first signal output end. The other of the third coil (j) is set to a second signal output end.
