An electrostatic atomization system for a vehicle includes an electrostatic atomization device that generates and emits charged micro-particle water from an emission port, a vehicle interior introduction port arranged in an instrument panel in a vehicle interior, and a communication duct that connects the emission port and the vehicle interior introduction port to emit the charged micro-particle water from the vehicle interior introduction port to the vehicle interior. The communication duct includes a first curved portion, which is arranged between the emission port and the vehicle interior introduction port and curved downward in a lower position than the vehicle interior introduction port, and a second curved portion, which is arranged between the first curved portion and the emission port and curved upward in an upper position than the first curved portion.
