Therefore, when the ceramic lattice is regarded as a flat plate, the first streaks are lined up on the first main surface side thereof, and the second main surface side opposite to the first main surface has a second streak portion. Lines are lined up.
- the cross section of the first strip portion has a flat shape on the first main surface side of the ceramic lattice body, and has a curved surface shape convex on the second main surface side.
- the second streak has a circular or elliptical cross section. Therefore, when a ceramics lattice is used as a setter on which a chip-shaped firing object is placed in a step of firing a firing object such as a ceramic electronic component, when firing a firing object that requires flatness, the ceramic lattice is used.
- the method of using the body with the first main surface facing up is adopted, and when it is desired to minimize the contact area with the object to be fired, the method of using the ceramic lattice body with the second main surface facing up is adopted (the method of using the ceramic lattice body with the second main surface facing up is adopted.

- each of the illustrated X-direction linear member and Y-direction linear member is circular, but may be elliptical, semicircular, triangular, quadrangular, or other polygonal. ..
- the setter for chip-shaped electronic components according to the present invention can be used not only in a firing process for manufacturing chip-shaped electronic components, but also in a plating process, a cleaning process, a drying process, and the like.
- the setter for chip-shaped electronic components When used in at least one of the plating process and the cleaning process, the setter for chip-shaped electronic components is required to have liquid permeability. Therefore, in this case, the wording of "breathable” used in the above description is replaced with the wording of "liquid permeability”.
