1. A first-stage ceramic collective board comprising:
a first-stage ceramic multilayer body, wherein
based on an X direction, a Y direction perpendicular to the X direction, and a Z direction perpendicular to the X direction and the Y direction, each of the X direction, the Y direction, and the Z direction having a positive side and a negative side,
the first-stage ceramic multilayer body includes
a plurality of first-stage ceramic layers that extend in the X direction and the Y direction and that are arranged side by side in the Z direction,
a plurality of first-stage first inner electrodes that are disposed between a pair of first-stage ceramic layers adjacent to each other in the Z direction among the plurality of first-stage ceramic layers and that extend in the X direction and the Y direction and are arranged side by side in the X direction with a first gap interposed therebetween, the first gap having a width A, and
a plurality of first-stage second inner electrodes that are disposed between a pair of first-stage ceramic layers adjacent to each other in the Z direction among the plurality of first-stage ceramic layers and that extend in the X direction and the Y direction and are arranged side by side in the X direction with a second gap interposed therebetween, the second gap having a width B, the pair of first-stage ceramic layers sandwiching the plurality of first-stage second inner electrodes being different from the pair of first-stage ceramic layers sandwiching the plurality of first-stage first inner electrodes,
the first-stage first inner electrodes each include a first cutout on at least one of end portions in the Y direction, the first cutout extending in the X direction and the Y direction and having the width B in the X direction,
the first-stage second inner electrodes each include a second cutout on at least one of end portions in the Y direction, the second cutout extending in the X direction and the Y direction and having the width A in the X direction, and
when the first-stage ceramic multilayer body is seen through in the Z direction, there are provided
a first region where the first gap and the second cutout overlap each other, and
a second region where the second gap and the first cutout overlap each other.
