A printed wiring board includes a resin insulating layer, and a first conductor layer including a fine wiring pattern and a thick-film wiring pattern. The magnetic tape head comprises a cluster of thin film inductive or magnetoresistive readwrite elements, an I-block preferably made of a ceramic material, a U-bar also preferably made of a ceramic material, and a base preferably made of a ceramic or metal material. One or more operational parameters or characteristics of the circuit or the device are derived. The cell gap g at the display pixel area is formed so as to be larger than spacers in the cell, and cell gaps of color layers overlapping the light shielding layer are made smaller than spacers. In either case, the movement of the magnet relative to the coil results in a voltage being induced on the coil according to Faraday’s law.
