Abstract: A tobacco product transaction management system suitable to manage transactions of tobacco products is provided. A tobacco product transaction management server receives identification information of a cigarette and a user ID of a transactor of the cigarette from a mobile terminal, and registers, in a distributed ledger recorder, a transaction history related to a transferor user and transferee user of the cigarette and associated with the received identification information, the transaction history including the received identification information and user ID. Moreover, a server receives identification information from the mobile terminal, acquires a transaction history associated with the received identification information from the distributed ledger recorder, and calculates the value of the cigarette on the basis of the acquired transaction history. The value of the cigarette is displayed on the mobile terminal.

Abstract: A guide wire includes (1) a core shaft, (2) a coil body covering a distal end portion of the core shaft and having spirally wound multiple element wires, and (3) a distal end fixed portion by which a distal end of the core shaft is fixed to a distal end of the coil body. The distal end of the coil body includes (i) a fixed portion in which adjacent ones of the multiple element wires are fixed to each other and (ii) a gap portion in which adjacent ones of the multiple element wires are not fixed to each other to provide a gap between the adjacent ones of the multiple element wires in the gap portion, as viewed in a cross section that is perpendicular to a longitudinal axis of the guide wire. The distal end fixed portion enters into the gap portion.
