PROBLEM TO BE SOLVED: To provide conductivity-imparting particles used for electrical connection between an LCD(liquid crystal display) or a PDP(plasma display) and a circuit board mounted with its drive circuit and to provide an anisotropically conductive adhesive using the same. SOLUTION: This conductivity-imparting particles A are made by covering surfaces of conductive particles 1 with an insulating resin 2, and the conductive particles 1 are made by applying metal plating 13 to surfaces of acrylic resin particles each comprising a flexible nucleus 11, and a shell 12 harder than the nucleus and coating the nucleus 11. The anisotropically conductive adhesive B is made by dispersing the conductivity-imparting particles A in an insulating adhesive 3. The anisotropically conductive adhesive is low in initial connection resistance, superior in reliability of connection over a long period of time, and moreover superior in short circuit (leakage) prevention.
