POROUS CERAMIC PARTICLE AND POROUS CERAMIC STRUCTURE
A porous ceramic particle (16) has a pair of main surfaces (161, 162) in parallel with each other. An average porosity in a range (633) extending from one main surface (161) toward the other main surface (162) and having a thickness which is one fourth of a particle thickness that is a distance between the main surfaces is higher than that in a range (632) which is positioned in the center between the pair of main surfaces and has a thickness which is half of the particle thickness. The upper main surface (161) is a surface to be placed on an object. By limiting an area having a high porosity to the vicinity of the one main surface (161), it is possible to cause the porous ceramic particle (16) to have low thermal conductivity and low heat capacity and suppress a decrease in the mechanical strength.
