Claims (4)

セル壁で構成された複数の筒状のセルと、セルの軸心方向においてセルの両側を交互に封止する封止体とを有するセラミックハニカムフィルタであって、前記封止体として、前記セル壁が焼成される前に既に焼成されてなるセラミックス焼成体を含むことを特徴とするセラミックハニカムフィルタ。 A ceramic honeycomb filter having a plurality of cylindrical cells formed of cell walls and a sealing body that alternately seals both sides of the cell in the axial direction of the cell, wherein the sealing body includes the cell A ceramic honeycomb filter comprising a ceramic fired body that is already fired before the wall is fired. 前記セラミックス焼成体の断面寸法は、焼成前におけるセルの断面寸法より小さく、焼成後におけるセルの断面寸法より大きく形成されていることを特徴とする請求項１に記載のセラミックハニカムフィルタ。 The ceramic honeycomb filter according to claim 1, wherein a cross-sectional dimension of the ceramic fired body is smaller than a cross-sectional dimension of the cell before firing and larger than a cross-sectional dimension of the cell after firing. 前記セラミックス焼成体は軸心方向においてセルの中間部に配設されていることを特徴とする請求項１又は２のいずれかに記載のセラミックハニカムフィルタ。 3. The ceramic honeycomb filter according to claim 1, wherein the ceramic fired body is disposed at an intermediate portion of the cell in the axial direction. 複数のセルを備え、軸心方向においてセルの両側を交互に封止体で封止したセラミックハニカムフィルタの製造方法であって、複数のセルを備えたハニカム成形体を押出し成形するとともに、成形中におけるハニカム成形体の所定のセルに既に焼成されてなるセラミックス焼成体を含む封止体を挿入する成形工程を含むことを特徴とするセラミックハニカムフィルタの製造方法。
A method for manufacturing a ceramic honeycomb filter comprising a plurality of cells and alternately sealing both sides of the cells with a sealing body in the axial direction, wherein the honeycomb formed body having a plurality of cells is extruded and molded. A method for manufacturing a ceramic honeycomb filter, comprising: a forming step of inserting a sealing body including a ceramic fired body that has already been fired into a predetermined cell of the honeycomb formed body.
