Structure, method of forming structure, and method of laser processing objects

A structural body comprising:

• an outer layer formed of a resin which transmits light with a specific wavelength,
• a plurality of inner layers formed of different resins stacked together and disposed on the outer layer, at least one of the inner layers being formed of a resin which does not transmit light with the specific wavelength, and
• a fine periodic structure formed on at least part of a surface of said at least one of the inner layers facing the outer layer and having a plurality of photodecomposition generated convex and concave portions,
• wherein the plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.

A structural body comprising:

• an inner layer formed of a resin which does not transmit light with a specific wavelength;
• an outer layer stacked on both surfaces of the inner layer, and having a first outer layer formed on one surface of said inner layer and a second outer layer formed on another surface of the inner layer, at least one of the outer layers being formed of a resin which transmits the light with said specific wavelength;
• and
• a fine periodic structure having a plurality of photodecomposition generated convex and concave portions formed on at least part of a surface opposed to the first outer layer and/or on at least part of a surface opposed to the second outer layer,
• wherein the plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.

A structural body comprising:

• a plurality of inner layers stacked together and formed of resins different from each other, at least one of the inner layers being formed of a resin which does not transmit light with a specific wavelength,
• a first outer layer formed on one side of said inner layers and a second outer layer formed on another side of said inner layers, the first outer layer and/or the second outer layer being formed of a resin which transmits light with the specific wavelength,
• a fine periodic structure formed on at least part of a surface of the inner layers facing the first outer layer or at least part of a surface facing the second layer, and having a plurality of photodecomposition generated convex and concave portions,
• wherein the plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.
