Abstract: An accounting processing method executed by an accounting device includes a receiving step of receiving an input of a customer identifier for identifying a customer who performs accounting, an acquiring step of acquiring, from a storage device that stores registration data by store including transaction data indicating details of a purchase target commodity, a customer identifier of the customer who purchases the commodity, and a store identifier for identifying a store that sells the commodity, the registration data by store including the customer identifier received in the receiving step, an accounting step of executing accounting processing for the purchase target commodity based on the registration data by store acquired in the acquiring step, and an output step of outputting the details of the purchase target commodity for each the store identifier based on the registration data by store acquired in the acquiring step.

Abstract: Provided is a printed circuit board which includes: a first dielectric layer including a first principal surface and a second principal surface on a side opposite to the first principal surface; a first adhesive layer formed on the first principal surface; a first metal foil pattern formed on the first adhesive layer and forming a signal line; and a second metal foil pattern formed on the second principal surface and forming a ground layer, in which the first metal foil pattern has a higher specific conductivity than a specific conductivity of the second metal foil pattern.
