Abstract
A sensor unit is configured to have an insulating case covering a mobile phone, a conductive substrate provided on the inner surface of the case, and a sensor electrode fixed on the surface of the conductive substrate. When a part of the human body of a user, such as a finger or a hand of the user, touches the surface of the case, a detection unit detects a change in capacitance provided between the human body and the conductive substrate. When it is determined that the user has touched the mobile phone, an activation signal is output and the operation mode of the mobile phone is set to a normal power mode in which power is automatically supplied. With this configuration, the operability of the mobile phone can be improved.
