その後、得られた9つのパターンを60分間、130℃の熱風オーブン内でいずれもキュアして、L/Sの値が異なる9種類の導電パターンをそれぞれ得た。
PETフィルム上に導電ペーストを乾燥膜の膜厚が7μmになるように塗布し、得られた塗布膜を100℃の熱風オーブン内で5分間乾燥した。図1に示すパターンの透光部Aを有するフォトマスクを介して乾燥後の塗布膜を露光、現像して、パターンを得た。その後、得られたパターンを60分間、130℃の熱風オーブン内でキュアして、比抵抗測定用の導電性パターンを得た。得られた導電性パターンのライン幅は0.400mmであり、ライン長さは80mmであった。
比抵抗 = 抵抗値×膜厚×線幅/ライン長 ・・・ (1)
