HOLDER

PROBLEM TO BE SOLVED: To provide a holder in which degradation of power transmission efficiency is suppressed while a charged device is being held.SOLUTION: Relating to a case 21, insert parts 22b-25b are inserted in the case 21 for relative movement. At end parts of the insert parts 22b-25b, outside the case 21, holding parts 22a-25a are formed. Thus, the holding parts 22a-25a are movable relative to the case 21 by way of the insert parts 22b-25b. By moving the holding parts 22a-25a relative to the case 21, a distance among the holding parts 22a-25a is matched with the size of a portable terminal 50. Thus, the portable terminal 50 is held by respective holding parts 22a-25a. Further, the case 21 can be moved relative to the portable terminal 50 present among the holding parts 22a-25a. Therefore, a primary coil L1 housed in the case 21 can be aligned with the position of the secondary coil of the portable terminal 50.
