The sensor element includes an element main body having a side surface, a porous layer and a water-penetration reduction portion that cover at least a front end-side part of the side surface. The water-penetration reduction portion disposed on the side surface so as to divide the porous layer or to be located closer to the rear end than the porous layer, an overlap length W that is the length of a continuous overlap between a range in which the water-penetration reduction portion is present in a longitudinal direction and a range in which inner peripheral surfaces of the one or more dense bodies are present in the longitudinal direction being 0.5 mm or more, and having a dense layer covers the side surface, the water-penetration reduction portion reduces the capillarity of water.
