Heat ray shielding particles are provided that are composite tungsten oxide particles having a hexagonal crystal structure represented by a general formula Li.sub.xM.sub.yWO.sub.z, wherein the element M in the general formula is one or more kinds of elements selected from alkaline earth metals and alkali metals other than lithium, 0.25≦x≦0.80, 0.10≦y≦0.50, and 2.20≦z≦3.00.

A coating including polycarbonate-unit-containing polyurethane resin and 5 mass % or more of nonvolatile matter is applied to a traveling metal strip in a state in which the surface temperature of the metal strip is 60° C. or lower. Next, the coating applied to the metal strip is baked at 80-250° C., and a coating film having a film thickness of 0.3 μm or greater is formed on the traveling metal strip. The proportion of polycarbonate units to the total mass of resin in the coating film is 10-80 mass %. The traveling metal strip is then wound after being cooling to a surface temperature of 80° C. or lower.

Provided is a phosphor, which is excited by a wide band of visible light, capable of emitting near-infrared light of high intensity. The phosphor comprises a crystal phase represented by a formula (1): MCuSi.sub.2O.sub.6 (where M comprises one or more of Ba, Sr and Ca), and a crystal phase represented by a formula (2): MCuSi.sub.4O.sub.10 (where M comprises one or more of Ba, Sr and Ca), wherein a ratio β of a diffraction peak intensity of MCuSi.sub.4O.sub.10 with respect to a diffraction peak intensity of MCuSi.sub.2O.sub.6 in an X-ray diffraction (XRD) pattern obtained by powder XRD measurement using CuKα rays is 0<β≦0.50.

The present invention may provide a screen used for screen golf, which can improve the brightness and clarity of the image projected on the screen by suppressing the light of the image from passing through the screen and increasing the reflectance of light from the front of the screen when an image is output by a projector on the screen. In addition, despite repeated golf shots of many users, the brightness and clarity of the image projected on the screen may not be damaged.

A conductive paste that includes conductive particles and a solvent. The solvent has a Hansen solubility parameter with an SP value of 24 to 39, a hydrogen bond term δh of 15 or more, and a polarity term δp of 7 or more. The conductive paste is applied to an unfired laminated body having laminated ceramic green sheets and internal electrode layers.
