ABSTRACT:
An infrared rays detecting apparatus is disclosed wherein the area of a loop provided by an element line and a grounding line formed on an inner tube is minimized to reduce an induced electromotive force to minimize production of noises so that correct detection can be accomplished. A grounding line is interposed for each arbitrary number of element lines on a surface of the inner tube, and the element lines are individually connected to output electrodes of an infrared rays sensor of the multi-element type while the individual grounding lines are connected to a common grounding electrode of the infrared rays sensor.
