This anisotropic connected structure connects terminals of a first electronic component and terminals of a second electronic component via an anisotropic conductive material. In the anisotropic connected structure, the terminals of the first electronic component have a hard metal part and a soft metal part that is softer than the hard metal part. The anisotropic conductive material has conductive particles, and the soft metal part is in contact with the conductive particles. The hard metal part is in contact with wiring of the first electronic component, and the hardness of the hard metal part is Hv 100 - 650. The hardness of the soft metal part is Hv 10 - 100. The hardness of the conductive particles is 5,880 N/mm2 - 26,460 N/mm2.
