摘要：
A host unit in a wireless power transmission system transmits power to a secondary unit during a communication-directivity control period and a power transmission period that are temporally divided from each other. The host unit transmits power such that a transmission output power of a power transmission radio wave during the power transmission period is greater than a transmission output power of a communication signal during the communication-directivity control period.
