The vibration power generator includes: a plurality of permanent magnets () integrated together to have given inter-magnet gaps under a state in which the same poles of the permanent magnets are opposed to each other; and a plurality of coils () arranged on respective outer peripheries of the plurality of permanent magnets so as to have a distance from the plurality of permanent magnets, and is configured to generate an electric power through relative movement of the plurality of permanent magnets and the plurality of coils. A relationship between a length of the opposed coils and a length of the permanent magnet is set so that the length of the coils is larger than the length of the permanent magnet and equal to or smaller than a sum of the length of the permanent magnet and a length of the inter-magnet gap.
