    • Provided are high thermal conductive boehmite, which has the characteristics of boehmite such as flame retardancy and high filling and yet has an improved thermal conductivity, and a method for manufacturing the high thermal conductive boehmite. The high thermal conductive boehmite is characterized by having thermal conductivity calculated in accordance with the following Mathematical Formula 1 of 11.0 W/m·K or greater; 1 - Vf = λc - λf / λm - λf × λm / λc ∧ 1 / n n = 3 / ψ (with the proviso that, Vf represents the volume filling ratio of boehmite, λc represents the thermal conductivity (W/m·K) of a boehmite-resin composite, λf represents the thermal conductivity (W/m·K) of boehmite, λm represents the thermal conductivity (W/m·K) of the resin, n represents the shape factor of filler particles proposed by Hamilton and Crosser, ψ represents a value calculated by dividing the surface area of a sphere that has the same volume of a boehmite particle volume by the surface area of an actual particle, and ^ represents exponentiation).
