Sudden acceleration of a passenger car is prevented at a time of starting to move during brake release operation. An elevator according to the present invention includes: a passenger car; a solenoid coil, a brake device which brakes the movement of the passenger car; a brake power supply; a moving velocity detection means which detects the moving velocity of the passenger car; and a controller which controls a current supplied by the brake power supply according the moving velocity of the passenger car detected by the moving velocity detection means, in which the controller transmits, to the brake power supply, a command for increasing a current (brake current i) supplied to the solenoid coil of the brake device by a predetermined value every time a predetermined time elapses when the passenger car is stopped, and transmits, to the brake power supply, a command for stopping increasing the current (brake current i) supplied to the solenoid coil of the brake device when a velocity change of the passenger car is detected by the moving velocity detection means.
