Abstract: An electromagnetic wave sensor includes: a first wire which extends in a first direction; a second wire which extends in a second direction different from the first direction; and an electromagnetic wave detector which is electrically connected to the first wire and is electrically connected to the second wire, wherein the second wire is provided so as to leave an interval with respect to the first wire in a third direction orthogonal to the first direction and the second direction, and the second wire is disposed to three-dimensionally intersect the first wire. At least one wire of the first wire and the second wire includes a wide portion, which is wider than an average value of a width of a portion excluding an overlapping portion of the at least one wire, in the overlapping portion in which the first wire and the second wire overlap each other.

Abstract: An element array circuit includes one or more first wiring lines, second wiring lines, impedance elements, one or more operational amplifiers, one or more conversion elements, and one or more switchers. The second wiring lines each extend in a direction different from a direction of extension of the first wiring lines. The impedance elements are each coupled to one each of the first and second wiring lines. The operational amplifiers each include a positive input terminal, a negative input terminal couplable to one of the second wiring lines, and an output terminal. The conversion elements are each coupled to the negative input terminal and the output terminal, and each convert a current flowing through the second wiring line coupled to the negative input terminal into a voltage. The switchers are each coupled to one of the conversion elements and come into a conducting state or a nonconducting state.
