An infrared detector comprises an array of detector elements (2) of the type having a layer of pyroelectric material (4)sandwiched between upper and lower electrodes (6,8) and separated along each edge by separations (16). The electrical sheet resistance of the upper electrode array (6) is reduced by forming gold rims (24) on the edges of the electrodes (6) around the periphery of each separation (16).
