Abstract
【解決手段】温度センサ素子10において、内部電極25a,25b上にリード線15a,15bをペーストで補強する際、内部電極に溶接接続されたリード線の全体を補強ペーストによって被覆せず、リード線の一方側面(片側面部)33を補強ペースト31aで被覆し、他方側面を補強ペーストで覆わない構造にする。これによりクラックの発生原因を除去して、内部電極とリード線との十分な接合強度の確保と導電性の補強を可能とする。
【選択図】図2
Description
<変形例1>
上記の実施の形態例に係る温度センサ素子では、図2および図3に示すように、リード線15aの一方側面側33における補強ペースト31aによる被覆領域が、そのリード線15aの頂上部近傍に達しているが、被覆する領域はこれに限定されない。例えば、図4に示すようにリード線15aの一方側面側における補強ペースト41で覆われる領域を、そのリード線の頂上部(図中、符号Sで示す)に至らないように縮小して、その補強ペースト41により内部電極25aとリード線15aとを接合してもよい。こうすることで、補強ペーストの充填量を抑制し、最少量の補強ペーストで内部電極とリード線との接合強度を確保できる。
リード線に対する補強ペーストによる補強箇所について、図2および図3に示す例では各リード線に対して1箇所としたが、これに限定されない。個々の補強ペーストがリード線の一方側面側と内部電極の片側上面とを覆う構成をとる限り、リード線の一方側面側の2箇所に補強箇所を設けてもよい。例えば、図5(a)に示すように2箇所に形成した補強ペースト43,45で、リード線15aの一方側面側と内部電極25aの片側上面とを覆う構成としてもよい。
