A pattern-forming method includes forming a partitioning layer on a foundation layer; forming a partitioning from the partitioning layer by patterning; and ejecting droplets containing a pattern-forming material onto a pattern-forming area that is enclosed by the foundation layer and the partitioning to form a pattern on the foundation layer. The detector detects a wireless frame which has a received power level higher than a carrier detection threshold when the wireless frame is received. Electronic supports and electronic circuit boards comprising at least one prepreg or at least one laminate. A minimum cost is determined from the costs associated with respective entries of the plurality of entries to the current position of the vehicle, and a first-priority entry is determined from the minimum cost. The host computer also corrects the measured data in view of a calibration curve and degradation based on the production lot information of the reagents stored in correspondence with the reagent ID number.
