摘要： A technique capable of immediately reporting to an operator an occurrence of abnormality in an electric tool is provided. A communication terminal 100 includes a communication-terminal-side control unit that determines whether abnormality has occurred in any of electric tools 10, 200, 300, and 400 based on information acquired from the electric tools 10, 200, 300, and 400 via wireless communication. When the communication-terminal-side control unit determines the occurrence of abnormality in any one of the electric tools 10, 200, 300, and 400, the occurrence of abnormality in the electric tool 10, 200, 300, or 400 is reported by at least one of a report unit included in the electric tools 10, 200, 300, and 400 other than the electric tool 10, 200, 300, or 400 in which the occurrence of abnormality is determined and a report unit included in the communication terminal 100.
