A liquid discharge head comprises a discharge port forming member having formed therein a discharge port arranged corresponding to an energy generating element which generates energy to eject a liquid and a flow path forming member for forming a flow path to supply ink to the discharge port. Said device comprises a plurality of antennas for communicating, together comprising an antenna arrangement. The calibration process is performed while the fluid sample is not being agitated. A first set of electrical traces are fabricated within the MCM package and coupled to the first GRS interface circuit and to the second GRS interface circuit. To solve such a problem, electrodeposited copper foil with carrier foil with a primer resin layer comprising a bonding interface layer, a bulk copper layer, a plated Ni\u2014Zn alloy layer and a primer resin layer which is formed in this order at least on one surface of the carrier foil is applied.
