PROBLEM TO BE SOLVED: To provide an information terminal by which failure analysis and a test are performed when a failure occurs. SOLUTION: Operation procedures and operation timing of the information terminal are stored in a storage part as history information (S203, S204). Though old operation procedures and old operation timing are deleted when exceeding predetermined capacity, the operation procedures and the operation timing stored near a failure generation point are stored as a failure log when the failure occurs (S208, S209).
