Abstract
A visible light communication apparatus includes: a light source; a power source circuit which applies a voltage to an electric path for causing the light source to emit light; a modulation circuit which causes the light source to emit light modulated by a communication signal; and a function circuit section which is connected to the electric path and performs a predetermined function by operating on a current flowing through the electric path, the function circuit section operating on a voltage lower than a first voltage value which is a lowest voltage value at which the light source emits light and higher than or equal to a second voltage value, wherein the power source circuit further applies to the electric path the voltage lower than the first voltage value and higher than or equal to the second voltage value.
