1. A rainfall amount measurement apparatus mounted to a vehicle, comprising:
a detector configured to generate an output corresponding to the attachment amount of raindrops,
an information acquisition unit configured to acquire raindrop amount information corresponding to an attachment amount of raindrops attached to an outer wall surface of a windshield of the vehicle in a measurement period based on the output of the detector, the raindrop amount information being used to set a wiping interval in a wiper wiping the raindrops attached to the outer wall surface;
a calculation unit configured to calculate a measurement value of a rainfall amount per unit time based on the raindrop amount information acquired by the information acquisition unit; and
an output unit configured to output the measurement value calculated by the calculation unit to a communication unit configured to communicate with an external device disposed outside of the vehicle.
