A method for controlling a continuously variable transmission that controls flow of oil into and out of a primary pulley oil chamber by use of an electric oil pump disposed in an oil passage between the primary pulley oil chamber and a secondary pulley oil chamber such that the electric oil pump has a first discharge port connected to the secondary pulley oil chamber, and a second the other discharge port connected to the primary pulley oil chamber via an oil passage switching valve, the method comprising:

• switching the oil passage switching valve in accordance with a vehicle driving state between a first switching position in which the primary pulley oil chamber and the second discharge port are connected, and a second switching position in which the primary pulley oil chamber and the second discharge port are disconnected and in which the second discharge port and an oil passage connecting an oil reservoir and the oil passage switching valve are connected;
• and
• opening an openable and closable leak valve provided in an oil passage between the electric oil pump and the oil passage switching valve and discharging a part of the oil that is discharged from the electric oil pump from the oil passage between the electric oil pump and the oil passage switching valve when switching between the first switching position and the second switching position.
