Sensor unit for gas sensor, has through holes arranged in substrates such that each of through holes in one of substrates is displaced opposite to each of through holes in another substrate, and conducting paths arranged between substrates

摘要

The unit has a sensor body (10) comprising conducting paths (21, 29, 30) arranged between substrates (11, 12). Through holes (22, 31, 32) are inserted into the substrates, and are lined with electrically conducting material, where the through holes establish a through-connection between the conducting paths. The through holes are arranged in the substrates in such a manner that each of the through holes in the substrate (11) is displaced opposite to each of the through holes in the substrate (12).
