The protective case contains a body including a through hole defined therein and a metal plate disposed in the through hole, a Nano heat dissipation layer formed on a back surface of the metal plate, such that the electronic equipment retains with a protective case and contacts with the metal plate. The metal plate has an external rim retained in the body. The body also includes a recess defined thereon, and the metal plate adheres with the recess. The protective case also contains a dissipating piece, and a back surface of the dissipating piece connects with a front surface of the metal plate, a front surface of the dissipating piece contacts with the electronic equipment.
