1. An accelerator pedal apparatus in which an acceleration operation for a vehicle is to be performed by a pedal of the vehicle, the pedal being configured to be operated by a foot, the accelerator pedal apparatus comprising:
a vibration application unit including a vibrator configured to apply vibration to the pedal; and
a vibration application control processor configured to;
generate a first vibration application waveform comprising one or both of a frequency component that is higher than or equal to 10 hertz and lower than or equal to 50 hertz and a frequency component that is higher than or equal to 100 hertz and lower than or equal to 300 hertz;
determine a gain based on control information of the vehicle;
generate, based on multiplying the first vibration application waveform by at least the gain to adjust an amplitude of the vibration application waveform, a second vibration application waveform; and
cause the vibration application unit to apply the vibration to the pedal with the second vibration application waveform,
wherein the control information of the vehicle includes at least one of: information on a vehicle speed of the vehicle; information on an operation speed of the pedal being a speed of an operation received by the pedal; and information on a vibration input to the vehicle from a road surface of a road where the vehicle travels.
