Abstract
Official abstract text for this publication.
An electric resistor includes a particle continuous body in which a plurality of conductive particles are connected, and a matrix disposed around the particle continuous body. The particle continuous body has surface-joined portions in which surfaces of the conductive particles are joined to each other. Silicon particles are preferably used as the conductive particles. The average boundary line length of the surface-joined portions is preferably 0.5 μm or more.
First claim
