Abstract:
1. A detector comprising: a semiconductor chip formed with a plurality of photodetector elements and provided with a plurality of output terminals of said photodetector elements on a surface thereof, a circuit substrate provided with a plurality of input terminals to which signals from said output terminals are input, and connecting means for connecting said respective output terminals to said respective input terminals; wherein the interval between said input terminals is set to a smaller dimension than the interval between said output terminals, wherein said circuit substrate comprises a signal reading circuit for reading out signals from said input terminals, said signal reading circuit being provided in a region outside the region in which said input terminals are formed such that none of said input terminals is located directly above or directly below said signal reading circuit, and wherein a plurality of first metal wires for connection to external leads are electrically connected to said circuit substrate and arranged outside the region where the input terminals are formed such that none of said input terminals is located directly above or directly below said first metal wires.
