The utility model provides a thermistor element. The utility model provides a thermistor element which can be well mounted on a mounting substrate through wire bonding and can improve connection reliability. The thermistor element includes: a body including a first end surface, a second end surface, a top surface, and a bottom surface, the second end surface being located on the opposite side of the first end surface, the top surface intersecting the first end surface and the second end surface, and the bottom surface being located on the opposite side of the top surface; a first external electrode covering the first end surface, a portion of the top surface, and a portion of the bottom surface; a second external electrode covering the second end surface, a portion of the top surface, anda portion of the bottom surface; a first internal electrode provided in the element body and connected to the first external electrode; and a second internal electrode that is provided inside the element body and is connected to the second external electrode. The first external electrode and the second external electrode include an outermost metal plating layer. The green body has a groove in a region exposed from the first external electrode and the second external electrode.
