The partial structure is formed of an opaque coating for exhibiting light-absorbing properties, on the side that faces the coating layer. The partial structure is formed of metallic coloration on the side that faces away from the coating layer. The partial structure is provided with a light-absorbing metallic layer (4) and a reflective metallic layer (5). Independent claims are included for the following: (1) method for manufacturing security element; and (2) use of the security element.
