To provide a pyroelectric light detection device that can suppress noise due to power source variations even when pyroelectric currents are output from a plurality of pyroelectric elements, and further to provide an electronic apparatus.
A pyroelectric light detection device includes: a sensor array that has pixels arranged in a matrix of N rows, where N is an integer of 1 or more, and M columns, where M is an integer of 2 or more, and pyroelectric photodetectors provided on respective pixels arranged in the matrix of N rows and M columns; N row lines WL; and M column lines DL. Each of the pyroelectric photodetectors includes a pyroelectric body interposed between a first electrode and a second electrode. When two regions adjacent to each other in a row direction and/or in a column direction in the sensor array are defined as a first region and a second region, the pyroelectric photodetectors of all the pixels in the first region are polarized in a first polarization direction, and the pyroelectric photodetectors of all the pixels in the second region are polarized in a second polarization direction opposite to the first polarization direction.
