Abstract: An object of the present invention is to provide a high-aspect-ratio plate-like alumina particle having low aggregability and high dispersibility and a method for producing the particle. The above problem is solved by providing a plate-like alumina particle including a step of firing an aluminum compound in the presence of a shape-controlling agent and a molybdenum compound serving as a fluxing agent. The above problem is solved also by providing a method for producing a plate-like alumina particle, the method including a step in which the aluminum compound and the molybdenum compound react with each other to form aluminum molybdate and a step in which the aluminum molybdate is decomposed to obtain the plate-like alumina particle.
