A method for manufacturing a p-type gallium nitride compound semiconductor includes providing a gallium nitride compound semiconductor containing a p-type impurity on a surface of a conductive substrate, immersing in an electrolytic solution the conductive substrate on which the gallium nitride compound semiconductor is provided, providing a cathode to be in contact with the electrolytic solution, and applying a current between the cathode and the conductive substrate serving as an anode to activate the p-type impurity.
