PURPOSE: A power generation device for a walking board is provided to increase power generation efficiency by generating inductive voltage at an upper coil and a lower coil in twice when the feet of pedestrians press to or separate from an upper plate. CONSTITUTION: A power generation device for a walking board comprises an upper plate (10), a lower plate (20), a permanent magnet assembly, a coil stator (60), an upper spring (50a), a lower spring (50b), and a movement transfer assembly. The permanent magnet assembly is installed between the upper and lower plates. The coil stator comprises an upper coil (62a) and a lower coil (62b) to generate current according to the lifting of the permanent magnet assembly. The upper and lower springs make the center of the permanent magnet assembly position on a boundary surface (A) of the upper and lower coils in a state where external force is not applied to the upper plate and always push the center of the permanent magnet assembly toward the boundary surface when the permanent magnet assembly is lifted up and down. The movement transfer assembly transfers the lifting force of the upper plate to the permanent magnet assembly.
