ABSTRACT:
Hollow polymer particles are provided to have an average particle diameter of 15 μm or more and 500 μm or less and a 10%-compressive strength of 1.5 MPa or more, and the hollow polymer particle includes a hollow portion in the interior. In addition, a porous ceramic filter is provided by firing a shaped material composed of a mixture in which the above-described hollow polymer particles are mixed to disperse in a ceramic composition.
