A circuit board device comprises a first wiring board ( 79 ) having plural first electrode terminals ( 73, 75, 77 ) for connection row-arranged on a surface layer, a second wiring board ( 87 ) having plural second electrode terminals ( 81, 83, 85 ) for connection row-arranged on a surface layer, and an anisotropic conductive member ( 89 ) disposed therebetween to the electrode terminals ( 73, 75, 77, 81, 83, 85 ). A local portion of each of the wiring boards ( 79, 87 ) has a step difference to divide and dispose the electrode terminals ( 73, 75, 77, 81, 83, 85 ). A local portion of the anisotropic conductive member ( 89 ) corresponding to the step difference has a step shape that is capable of contacting with the step difference. A laminate comprising respective wiring boards ( 79, 87 ) and the anisotropic conductive member disposed therebetween is pressed and held in a lamination direction.
