PROBLEM TO BE SOLVED: To provide an inexpensive laminated adhesion core ensuring space factor and core shape equivalent to or better than those of an adhesion film by not using an adhesion film but using a soft magnetic material of conventional insulation film, and to provide its production process. SOLUTION: The laminated adhesion core is produced through a step for forming a laminate by constraining a plurality punched soft magnetic steel plates with a forming jig such that the lamination surface becomes perpendicular to the bottom surface of the forming jig, a step for bonding the laminate by applying adhesive to the lamination end face under a state where the laminate is constrained by means of the forming jig, and a step for separating the bonded laminate to have a predetermined thickness using a jig.
