PROBLEM TO BE SOLVED: To provide an anisotropic electroconductive adhesive material surely carrying out conduction and connection at a low electric resistance value without causing short-circuiting even in conduction and connection in a high-definition device in which connection terminals are formed into fine pitches. SOLUTION: The anisotropic electroconductive adhesive material 2 formed on a base sheet 1 as a separator is composed by including a mesh member 23 as a particle movement regulating member for regulating the movement of electroconductive particles 22 in a binder resin layer 21 starting softening and flowing by being pressurized while being heated in the binder resin layer 21 in which the electroconductive particles 22 are uniformly dispersed and held. The mesh member 23 is formed of a thermoplastic resin material melting in the binder resin layer 21 without adversely affecting an adhesion holding ability of the binder resin layer 21 even by melting in a process of heating the binder resin layer 21 to a curing temperature.
