Abstract
Description
PTC特性を有するセラミック本体を含んでなる発熱体が提案される。前記発熱体は前記セラミック本体に配置された電極を有している。PTCとは、正の温度係数を表す。前記セラミック本体も前記電極も共に無鉛である。
様に応じ、直接前記セラミック本体または前記接点層に被着されていてよい。前記多層体は好ましくは、その下にある層の導電率よりも高い優れた導電率を有する導電層(外側接点層)を含んでいてもよい。導電層としては、たとえば銀層または銀含有層が適切である。さらに、ここに挙げられていないその他の多層体も本提案になる発熱体の前記電極用に思料可能である。
前記発熱体の抵抗率はたとえば10〜500オームcmに設定されていてよい。ただし、抵抗率は前記の範囲に制限されるものではない。
2,3 電極
2a,3a 内側接点層
2b,3b 拡散封止層
2c,3c 外側接点層
