PROBLEM TO BE SOLVED: To provide a new structure where metal particles can be regularly arranged with an arbitrary uniform size and an arbitrary arrangement, a method for manufacturing the structure, and a sensor using the same, to hereby improve and stabilize sensor sensitivity in the case of the use of the structure as a sensor, and further to provide new uses which can be found only by the new structure. SOLUTION: In a plasmon resonance device 100 as an example of the structure, mutually isolated metal particles 7 are formed in a plurality of pores 5 in anodically oxidized alumina 3, respectively. As the method for manufacturing the plasmon resonance device 100, metal is allowed to adhere to the anodically oxidized alumina 3 in which the plurality of pores 5 are opened and then the resultant metal adherend on the pore-opened surface of the anodically oxidized alumina 3 is removed. By this method, the mutually isolated metal particles can be formed in the respective plurality of independent pores. This plasmon resonance device 100 can be used as the sensor using a localized plasmon resonance phenomenon. COPYRIGHT: (C)2003,JPO
