う欠点がある。(Prior Art and its Problems) Conventionally, as a conductive resin composition, one in which a conductive solid powder such as carbon black is kneaded into a resin is known. However, in order to obtain high conductivity, a large amount of solid powder must be blended, and a decrease in mechanical strength, particularly impact strength, is unavoidable. On the other hand, polybutylene terephthalate (PB'l') has been attracting attention as a molding material for injection molding in recent years due to its excellent chemical resistance, low water absorption, and moldability. It has been recognized for its great utility value. However, PBT resin as a molding material has the disadvantage that its impact strength is low when notched due to its crystallization behavior, and when carbon black is added to give it conductivity, impact resistance is low. The disadvantage is that it cannot withstand practical use.

強度は減少し、耐衝撃性が不充分となるものであった。P B T (impact resistance of PB'r resin 1) As a method for improving the properties, alloying with a rubber component is being considered. For example, in Japanese Patent Application Laid-Open No. 49-970814
The impact strength of PBT co-fat has been improved by mixing it with a resin, but when carbon black is added to this composition, the impact strength decreases, resulting in insufficient impact resistance.
