description The present invention provides a laminated iron core which is unlikely to exhibit bonding failures between steel sheets even when the distance (thickness of adhesive layer) between the steel sheets is small. A laminated iron core according to the present invention which is obtained by layering a plurality of steel sheets with an adhesive layer interposed therebetween, wherein the adhesive layer is a heat-curable resin composition which contains an epoxy resin, an amino triazine novolac phenolic resin, an acrylic acid ester polymer, and inorganic particles which exhibit an average particle diameter of 10-100nm, inclusive, and a maximum particle diameter of 1 [mu]m or less. The volume content of the inorganic particles in the adhesive layer is 5-30 vol%, inclusive, the Young's modulus of the adhesive layer at 25 DEG C according to the nano-indentation method is 2-6 GPa, inclusive, and the distance between the steel sheets is 0.5-5 [mu]m, inclusive. 本发明提供即使钢板间的距离(粘接剂层的厚度)减小也不容易发生钢板间的接合不良的层叠铁芯。本发明的层叠铁芯是经由粘接剂层将多张钢
