Abstract
A ceramic porous sintered body including a plurality of ceramic coarse particles and a polycrystalline sintered body forming a bonding layer. The bonding layer exists between the ceramic coarse particles and connects the ceramic coarse particles. The polycrystalline sintered body includes a plurality of ceramic fine particles having an average particle size smaller than the ceramic coarse particles. The ceramic porous sintered body has an average pore diameter of 5 μm to 50 μm. A ratio of an average particle size of the ceramic coarse particle to the ceramic fine particles is 15:1-200:1.
