PROBLEM TO BE SOLVED: To provide a method for producing a plate-like silica particle having low relative permittivity and/or low dielectric loss tangent and having high anisotropy, and the plate-like silica particle. SOLUTION: (1) The method for producing the plate-like silica particle having the relative permittivity of≤3.5 and/or the dielectric loss tangent of≤0.01 includes a step of pulverizing a hollow silica particle in which nanopores are substantially not present and (2) the plate-like silica particle having the relative permittivity of≤3.5 and/or the dielectric loss tangent of≤0.01 is obtained by using the production method.
