Abstract
A PM detection sensor has a sensor body part made of an insulating member and a positive electrode and a negative electrode. The positive electrode is composed of a plurality of positive electrode segments. The negative electrode is composed of a plurality of negative electrode segments. A deposition surface is formed on the sensor body part. These electrode segments are formed on the deposition surface to be exposed to exhaust gas introduced into the inside of the PM detection sensor. The positive electrode segments and the negative electrode segments are arranged adjacently to and separately from each other, on the deposition surface, along a short width direction and a long width direction of each electrode segment. The short width direction and the long width direction are orthogonal to a normal direction of the deposition surface.
