摘要:
A multilayer electronic component that can suppress the formation of projections and depressions on a surface and an electronic component unit including the multilayer electronic component are provided.
Coil electrodes (8) having a shape of ring-shaped wiring with a part removed therefrom are electrically connected to each other to constitute a coil (L). Magnetic layers (4) are stacked together with the plurality of coil electrodes (8). The coil electrodes (8a, 8c, 8e) having a radius r1 and the coil electrodes (8b, 8d) having a radius r2 that is smaller than the radius r1 are alternately arranged in a stacking direction.
