The invention provides a catalyst for thermal decomposition of an organic substance having the form of spherical granule having a particle diameter of 0. The flexible member is molded around the electrical conductor and the antenna, while the electrical conductor is positioned such that it extends into the housing through the through-opening. The storage system has a control unit which sets the switch and a setting command preserving unit which keeps a command for setting the switch. Accordingly, the home appliance may externally output the acoustic signal as the sound so that the user may be easily notified of transmission.
