A notification sound generation device includes a speaker, a controller, a resistor, and a correction unit. The speaker is configured to generate a notification sound to surroundings of a vehicle. The controller is configured to output a sound signal that causes the speaker to generate the notification sound. The resistor has a resistance value corresponding to a correction amount for correcting a sound pressure variation of the speaker or a resistance value corresponding to a sound pressure value of the speaker. The correction unit is configured to correct the sound signal based on a physical quantity correlated with the resistance value of the resistor.
