  The terminal electrodes 5 to 8 are not arranged on the second main surface 2b, the third side surface 2e, and the fourth side surface 2f of the element body 2. For this reason, the second main surface 2b, the third side surface 2e, and the fourth side surface 2f of the element body 2 are exposed.

  As described above, in this embodiment, the length in the height direction of the element body 2 is set to be smaller than the length in the longitudinal direction and the length in the width direction, and the low profile of the multilayer capacitor array C1 is reduced. It is planned. The first to fourth terminal electrodes 5 to 8 have electrode portions 5 a to 8 a arranged on the first main surface 2 a of the element body 2, respectively. Therefore, the multilayer capacitor array C1 can be electrically connected to the wiring formed on the substrate on the first main surface 2a side of the element body 2, and can be easily built in the substrate.

  The electrode portions 5a and 6a arranged on the first main surface 2a of the first and second terminal electrodes 5 and 6 are positioned side by side in the longitudinal direction of the element body 2 on the first main surface 2a and the element body 2 Therefore, the area of each electrode portion 5a, 6a can be set large.
