  • Patent number: 10488270
    Abstract: A temperature sensor element has such a structure as, when reinforcing lead wires on internal electrodes with a paste, one side surface of each of the lead wires is covered with a reinforcement paste and the other side surface is not covered with the reinforcement paste without covering the entire lead wires welded and connected to the internal electrodes. This allows elimination of cause of cracks generating, thereby securing sufficient joining strength and reinforcement of conductivity of the internal electrodes and the lead wires, and securing connection strength between the lead wires and the internal electrodes.
    Type: Grant
