Abstract This sensor element 20 is provided with an element body 60, an upper connector electrode arranged on a first surface 60a of the element body 60, and a protective layer 80 covering at least the front end side of the first surface 60a. The protective layer 80 has a first specific protective layer 92 with a thickness T1 of 10 μm or less, and the ratio T1/T2 of the thickness T1 and the thickness T2 of a front part 88 which is the front part of the first specific protective layer 92 in the protective layer 80 is 1.0 or less. La présente invention concerne un élément capteur (20) qui est pourvu d'un corps d'élément (60), d'une électrode de raccord supérieure disposée sur une première surface (60a) du corps d'élément (60), et une couche de protection (80) recouvrant au moins le côté extrémité avant de la première surface (60a). La couche de protection (80) a une première couche de protection spécifique (92) ayant une épaisseur T1 inférieure ou égale à 10 µm, et le rapport T1/T2 de l'épaisseur T1 sur l'épaisseur T2 d'une partie avant (88) qui est la partie avant de la première couche de protection spécifique (92) dans la couche de protection (80) est inférieur ou égal à 1,0. センサ素子20は、素子本体60と、素子本体60の第1面60aに配設された上側コネクタ電極と、第1面60aのうち少なくとも前端側を被覆する保護層80と、を備えている。保護層80は、厚さT1が10μm以下である第1特定保護層92を有し、厚さT1と保護層80のうち第1特定保護層92の前側部分である前側部分88の厚さT2との比T1/T2が1.0以下である。
