<P>PROBLEM TO BE SOLVED: To improve energy utilization efficiency by reducing energy disappearance caused by metal extinction generated in a compound by multiphoton excitation gold, in a multiphoton excitation device utilizing localized plasmon. Ž<P>SOLUTION: This multiphoton excitation device including a substrate 13 including a dielectric layer 12 having a plurality of fine holes 15 opened at least on one surface, and a plurality of fine metal bodies 14 formed in the fine holes 15, is constituted so as to include a plurality of multiphoton excitation complex compounds expressed by a general formula D-L-A bonded to the surface of the fine metal bodies 14. In this case, D is a multiphoton excitation portion having a π-electron conjugate system capable of generating multiphoton excitation by absorbing light energy of irradiation light P, and A is a bonding portion bonding to the fine metal body 14, and L is a connection group for connecting the multiphoton excitation portion D to the bonding portion A.
