Abstract

A method and apparatus for producing AlN whiskers includes reduced incorporation of metal particles, an AlN whisker body, AlN whiskers, a resin molded body, and a method for producing the resin molded body. The method for producing AlN whiskers includes heating an Al-containing material in a material accommodation unit to thereby generate Al gas; and introducing the Al gas into a reaction chamber through a communication portion while introducing nitrogen gas into the reaction chamber through a gas inlet port, to thereby grow AlN whiskers on the surface of an Al2O3 substrate placed in the reaction chamber.
