Claim 4:
5. A second-stage ceramic collective board comprising:
a second-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 second-stage ceramic multilayer body includes
a plurality of second-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 second-stage first inner electrode that is disposed between a pair of second-stage ceramic layers adjacent to each other in the Z direction among the plurality of second-stage ceramic layers and that extends in the X direction and the Y direction, and
a second-stage second inner electrode that is disposed between a pair of second-stage ceramic layers adjacent to each other in the Z direction among the plurality of second-stage ceramic layers and that extends in the X direction and the Y direction, the pair of second-stage ceramic layers sandwiching the second-stage second inner electrode being different from the pair of second-stage ceramic layers sandwiching the second-stage first inner electrode, and

when the second-stage ceramic multilayer body is seen through in the Z direction,
a first end portion of the second-stage first inner electrode in the X direction is separated from a first end portion of the second-stage ceramic multilayer body in the X direction,
at least one of end portions of the second-stage first inner electrode in the Y direction at a second end portion of the second-stage first inner electrode in the X direction is separated from a second end portion of the second-stage ceramic multilayer body in the X direction,
a central portion of the second-stage first inner electrode in the Y direction at the second end portion of the second-stage first inner electrode in the X direction overlaps the second end portion of the second-stage ceramic multilayer body in the X direction,
at least one of end portions of the second-stage second inner electrode in the Y direction at a first end portion of the second-stage second inner electrode in the X direction is separated from the first end portion of the second-stage ceramic multilayer body in the X direction,
a central portion of the second-stage second inner electrode in the Y direction at the first end portion of the second-stage second inner electrode in the X direction overlaps the first end portion of the second-stage ceramic multilayer body in the X direction, and
a second end portion of the second-stage second inner electrode in the X direction is separated from the second end portion of the second-stage ceramic multilayer body in the X direction.
