    摘要： A ceramic material has a characteristic length La of a micro-structure thereof that satisfies 0.1 LAMFP≦La≦100 LAMFP, and has thermal conductivity that monotonously increases from room temperature to 100° C., where LAMFP denotes apparent mean free path of phonons at room temperature, and is defined as LAMFP=(3×thermal conductivity)/(heat capacity×speed of sound). The characteristic length La of the micro-structure is an interval between particles of different type of material when the ceramic material includes a composite material in which the different type of material is dispersed in a base material, is an interval between one pore and another pore when the ceramic material includes a porous body, and is the crystalline particle size (interval between one grain boundary and another grain boundary) when the ceramic material includes a polycrystalline body.
