<P>PROBLEM TO BE SOLVED: To provide a detector, sensor device and electronic apparatus, capable of increasing detection sensitivity. <P>SOLUTION: The detector includes: a detection node ND, first to (n)th pyroelectric elements PY1 to PYn (n: an integer of two or more), and a detection circuit 20. The pyroelectric elements PY1 to PYn are provided in series between the detection node and a first power source node VSS. The detection circuit 20 is connected to the detection node ND. The first to (n)th pyroelectric elements PY1 to PYn are set so that the polarization directions are the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
