A pyroelectric element includes a plurality of electrodes (2,3) formed on one major surface of a pyroelectric film (1) and constituting a first group and at least one electrode (4,5) formed on the other major surface of the pyroelectric film (1) and constituting a second group. The directions of proximal end portions of lead portions of the electrodes (2,3;4,5) and widths of the proximal end portions are set to be a predetermined direction and a predetermined value such that effective light-receiving electrode areas of unit pyroelectric elements are substantially equal to each other even if electrode patterns of the first and second groups are slightly offset from each other.
