Patent Number: 
Section: claims

1. A scattered ray absorption grid comprising: a grid portion constituted by use of plate members formed in such a manner that a powder containing tungsten 50% by weight or more are hardened with a binder so that the powder has a spatial filling rate of 40% or more. 2. The scattered ray absorption grid according to  claim 1 , wherein said binder is organic binder. claim 1 3. The scattered ray absorption grid according to  claim 2 , wherein said organic binder is thermoplastic polyurethane resin. claim 2 4. The scattered ray absorption grid according to  claim 1 , wherein said binder is a metal with a melting point less than the melting point of tungsten. claim 1 5. The scattered ray absorption grid according to  claim 4 , wherein said metal is lead solder made of an alloy containing tin and lead as its main components. claim 4 6. A scattered ray absorption grid comprising; a grid portion constituted by use of plate members for constituting a grid formed in such a manner that, grid materials formed by hardening a powder containing tungsten 50% by weight or more with a binder so that the powder has a spatial filling rate of 40% or more is coated on a substrate. 7. The scattered ray absorption grid according to  claim 6 , wherein said binder is organic binder. claim 6 8. The scattered ray absorption grid according to  claim 7 , wherein said organic binder is a polymer resin. claim 7 9. The scattered ray absorption grid according to  claim 8 , wherein said polymer resin is unsaturated polyester resin. claim 8 10. The scattered ray absorption grid according to  claim 6 , wherein said binder is a metal with a melting point less than the melting point of tungsten. claim 6 11. The scattered ray absorption grid according to one of  claims 1  to  4 , wherein said spatial filling rate is equal to 60% or more. claims 1 4
