Abstract
A wireless power transmission system includes a first antenna, a second antenna configured to perform wireless power transmission with the first antenna, and a movement unit configured to move a position of the second antenna relative to the first antenna in a predetermined moving direction, wherein the second antenna is shorter in length in the moving direction than the first antenna, wherein a distance between at least one end portion of the first antenna in the moving direction and the second antenna at a position where the second antenna faces the end portion is longer than a distance between an intermediate portion of the first antenna and the second antenna at a position where the second antenna faces the intermediate portion, and wherein the intermediate portion of the first antenna is a portion of the first antenna excluding both end portions of the first antenna.
