A coral cultivation method includes: an electrodeposited-mineral precipitating procedure for precipitating electrodeposited minerals on a coral-growth substrate for growing coral, which is placed in seawater, by applying an electric current between the coral-growth substrate and a first anode that is electrically connected to the coral-growth substrate and placed in the seawater； a coral-larvae growing procedure for growing coral larvae on the coral-growth substrate precipitated with the electrodeposited minerals； a coral-cultivation-structure configuring procedure for configuring a coral cultivation structure from a plurality of the coral-growth substrates on which the coral larvae are grown； and a coral cultivating procedure for cultivating coral by applying an electric current between the coral-growth substrate on which the coral larvae are grown and a second anode.
