Description
ヒューズ部材を有して成るヒューズ素子であって、
ヒューズ部材は、それを電流が流れる場合の電流の流れ方向に沿って、少なくとも1つの酸素難アクセス領域(即ち、酸素が容易にアクセスできない領域)、および少なくとも1つの酸素易アクセス領域(即ち、酸素が容易にアクセスできる領域)を有して成ることを特徴とするヒューズ素子を提供する。これらの領域は、電流の流れ方向に沿って隣接して存在するのが好ましい。特に好ましい態様では、酸素難アクセス領域の両側に酸素易アクセス領域が存在する。即ち、酸素難アクセス領域が酸素易アクセス領域によって挟まれている。酸素易アクセス領域の数、および酸素難アクセス領域の数は特に限定されるものではなく、それぞれの数は、必要に応じて、2またはそれ以上であってよい。これらの領域は、ヒューズ素子を流れる電流の流れ方向に沿って存在する。従って、これらの領域は電気的には直列に接続されていることになる。
14…酸素遮断性要素(コーティングまたはフィルム)、16…酸素難アクセス領域、
18…酸素易アクセス領域、20…リード、22…空間部。
