Surface-enhanced raman scattering element
First Claim
1. A surface-enhanced Raman scattering element comprising:
- a substrate having a principal surface;
a molded layer having a support part formed on the principal surface of the substrate so as to extend along the principal surface and a fine structure part formed on the support part; and
a conductor layer formed on the fine structure part and constituting an optical functional part for generating surface-enhanced Raman scattering;
wherein the molded layer is relatively thinner in a direction intersecting the principal surface of the substrate at an outer edge part of a fine structure area formed with the fine structure part in the molded layer than at a center part of the fine structure area,the fine structure part is formed integrally with the support part, and consists of projections arranged into a two-dimensional array on the support part, andthe thickness of the molded layer in a projection formed in the center part of the fine structure area is greater than the thickness of the molded layer in a projection formed in the outer edge part of the fine structure area.

Abstract
A surface-enhanced Raman scattering element comprises a substrate having a principal surface; a molded layer having a support part formed on the principal surface of the substrate so as to extend along the principal surface and a fine structure part formed on the support part; and a conductor layer formed on the fine structure part and constituting an optical functional part for generating surface-enhanced Raman scattering; the molded layer being relatively thinner in a direction intersecting the principal surface of the substrate at an outer edge part of a fine structure area formed with the fine structure part in the molded layer than at a center part of the fine structure area.
