An insulating material having improved withstand voltage strength in a predetermined direction and improved toughness in a direction perpendicular thereto is provided. An insulating material includes a matrix resin 51, a layered compound 53, and fine particles 52, in which the layered compound 53 and the fine particle 52 are in a state dispersed in the matrix resin 51, the layered compound 53 in a plate or bar-like form is used with the major axes thereof being oriented in a predetermined direction, and a plurality of the fine particles 52 are agglomerated to form a dendritic structure and dispersed between adjacent layered compounds 53. |
