PROBLEM TO BE SOLVED: To provide portable radio equipment and a contactless charging system using the same that can shorten a charging time.SOLUTION: A mobile phone 1 notifies a user of deterioration in reception quality state of a radio wave by turning on an LED 10a when the absolute value |Q1-Q2| of a difference between a reception quality state Q1 in which electric power is not supplied from a contactless charger 11 and a reception quality state Q2 in which electric power is supplied from the contactless charger 11 is larger than a threshold value QTH and the reception level R2 of the radio wave is smaller than a threshold RYH. Therefore, the user can reduces deterioration in reception quality state by changing the position of the portable radio equipment 1 on the contactless charger 11 based upon the notification result. |
