The information presentation device includes: an amount-of-steering-operation detector configured to detect an amount of a steering operation by a driver; a steering gear ratio detector configured to detect the steering gear ratio; a vibration waveform generator configured to generate a vibration waveform; a vibrator configured to cause vibration of one or both of the air around an occupant and a member in contact with the occupant, using the vibration waveform; and a gain adjuster configured to increase an output gain of the vibration waveform in accordance with an increase in an absolute value of a differential value of a value obtained by multiplying the amount of the steering operation by a reciprocal of the steering gear ratio.",
