Abstract:
The present invention comprises: an element body (40) that is formed by layering base material layers (41, 42, 43); and coil elements (L1, L2, L3) that are provided inside the element body (40). Coil element (L1) is configured from the connection of coil patterns (11, 12, 13) that are correspondingly provided to the base material layers (41-43). Coil element (L2) is configured from the connection of coil patterns (24, 25, 26) that are correspondingly provided to the base material layers (41-43). Coil element (L3) is configured from the connection of coil patterns (37, 38, 39) that are correspondingly provided to the base material layers (41-43). When the element body (40) is seen from the layering direction (Z), coil patterns (11, 38, 26) substantially overlap, coil patterns (24, 12, 39) substantially overlap, and coil patterns (37, 25, 13) substantially overlap.
