PROBLEM TO BE SOLVED: To provide an infrared reflective pattern-formed body having such a property that, when a patterned portion thereof to reflect infrared rays is obliquely irradiated with infrared rays, a ratio of a reflectance in the patterned portion to reflect infrared rays at a wavelength showing the highest reflectance in an infrared region from 780 nm to 2500 nm to a reflectance of a non-patterned portion is large.SOLUTION: The infrared reflective pattern-formed body includes a patterned portion comprising an infrared reflective material, to reflect infrared rays, in at least some regions on a support body. The patterned portion to reflect infrared rays has a concavo-convex structure including a plurality of projections and/or recesses; the patterned portion to reflect infrared rays contains metal particles on a surface of the projections and/or the recesses in the concavo-convex structure; the metal particles contain hexagonal or circular planar metal particles by 60% by number or more; and the planar metal particles having a surface orientation in a range of 0° to ±30° of an angle, which is formed by a major plane of the planar metal particle and the surface of the concavo-convex structure closest to the planar metal particle, are included by 50% by number or more with respect to the whole planar metal particles.SELECTED DRAWING: Figure 17 |
