Abstract
An anisotropically conductive sheet can retain required conductivity over a long time even when used repeatedly, or used under a high -temperature environment. The sheet contains conductive particles exhibiting magnetism in a state oriented in a thickness-wise direction in an elastic polymeric substance having a durometer hardness of 20 to 90. The particles are coated with a lubricant or parting agent. In addition, the sheet has a long service life owing to its high durability and thermal durability.
