Zusammenfassung:Disclosed is a pyroelectric sensor array, which can be attached to a circuit board, and which is provided with a pyroelectric substrate, and a plurality of pyroelectric elements formed on the pyroelectric substrate. The pyroelectric substrate has the connecting surface placed on the circuit board. The pyroelectric elements are composed of edge pyroelectric elements disposed on the pyroelectric substrate edge portion in a predetermined disposing direction, and center pyroelectric elements disposed on the pyroelectric substrate center portion. Each of the pyroelectric elements is provided with two adjacent connecting electrodes that are formed on the connecting surface. The capacitance between the two connecting electrodes of each of the edge pyroelectric element is larger than the capacitance between the two connecting electrodes of each of the center pyroelectric elements.
