The present invention provides a conductive powder, which can show the high conductivity even in condition that a resin is included, and a conductive composition using the same. In such a conductive powder and a conductive composition, the conductive powder having a convex radically extended and a concave among the convex having the following features; (1) the convex and concave of the adjoining conductive powders are mutually press-fitted to form a conductive path(first feature). (2) the shape of the convex is at least one shape selected from the group essentially consisting of the needle shape, a rod shape and a petal shape(second feature). (3) the electrical resistivity is within a range of 5×10−6 to 1×10−3 Ω·cm in condition that a resin is included (third feature).
A conductive powder having a convex radically extended and a concave among the convex, wherein the said convex and concave of the adjoining conductive powders are mutually press-fitted to form a conductive path.
A conductive powder having a convex radically extended and a concave among the convex, wherein the shape of the convex is at least one shape selected from the group essentially consisting of the needle shape, a rod shape and a petal shape.
A conductive powder having a convex radically extended and a concave among the convex, wherein the electrical resistivity (epoxy resin 30 pbw./conductive powder 70 pbw.) is within a range of 5×10−6 to 1×103 Ω·cm in condition that a resin is included.
A conductive composition including a conductive powder having a convex radically extended and a concave among the convex and a resin, wherein the said convex and concave of the adjoining conductive powders are mutually press-fitted to form a conductive path.
A conductive composition including a conductive powder having a convex radically extended and a concave among the convex and a resin, wherein the shape of the convex is at least one shape selected from the group essentially consisting of a needle shape, a rod shape and a petal shape.
A conductive composition including a conductive powder having a convex radically extended and a concave among the convex and a resin, wherein the electrical resistivity (epoxy resin 30 pbw./conductive powder 70 pbw.) is within a range of 5×10−6 to 1×10−3 Ω·cm in condition that a resin is included.
