PROBLEM TO BE SOLVED: To provide a porous hollow particle which has an inorganic porous structure of a metallic compound and maintains the shell shape of a particulate biomaterial, its manufacturing method, and a functional member. SOLUTION: The porous hollow particle is made by precipitating the metallic compound on the surface of the particulate biomaterial or covering the surface with the metallic compound, has the porous structure of the metallic compound, and maintains the shell shape of the particulate biomaterial. The functional member contains the hollow particle as a component. The manufacturing method can easily manufacture micron-sized porous hollow particle of which the particle shape and particle diameter are relatively uniform by an environment-friendly method. The porous hollow particle can be suitability used as a particulate material for, for example, an adsorbent, a separation material, pigment, a cosmetic, a catalyst, and paint by using its characteristics, such as high adsorptive capacity, a high light-reflex property, and a high friction function.
