    Abstract: To provide a novel immobilized product in which a carbon material and/or a silicon material is/are immobilized on a base material surface by a chemical bond via a linking group, and a method for producing the same. The immobilized product is an immobilized product in which a carbon material is immobilizing on a surface of a base material, wherein the carbon material is chemically bonded on the surface of the base material via a linking group, and the linking group is at least one selected from the group consisting of a —NH group, a —NH—R1—NH group, a —SO group, a R2 group, a —O—R3—O group, and a R4 group (in which the R1 to R4 each independently represent at least one selected from the group consisting of a chain alkyl group, a cyclic alkyl group, a chain alkenyl group, a cyclic alkenyl group, a chain alkynyl group, etc.).
