PROBLEM TO BE SOLVED: To provide a radio wave absorption particles, a radio wave absorption paint and a radio wave absorber, incident to continuous expansion of the utilization range of radio waves, e.g., start of introduction of next generation wireless LAN(65GHz), rear-end collision prevention radar (76.5GHz), and the like.SOLUTION: Radio wave absorption particles includes inorganic hollow particles 10 having a cavity 12b surrounded by an external wall 12, and a conductive film 14 adhering to the outer surface 12a of the external wall 12. The median size of the inorganic hollow particles may be 10-100 μm. The thickness of the external wall may be 0.3-1.5 μm.SELECTED DRAWING: Figure 1 |
