<P>PROBLEM TO BE SOLVED: To provide a material for a gasket which can be discharged from a dispenser at ambient temperature and has an excellent shape holding property after being discharged, and also to provide a gasket, a hard disk device using the gasket, and a method for producing the gasket. <P>SOLUTION: The material for a gasket includes (A) an energy-ray curable liquid oligomer having a methacryloyl group, (B) a methacrylate monomer, and (C) an inorganic filler, and has a yield stress of ≥30 Pa and a viscosity (η<SB POS="POST">10</SB>) of ≤100 Pa s at a shear rate of 10 s<SP POS="POST">-1</SP>. The gasket obtained by irradiating the material for a gasket with an active energy ray, the hard disk device which uses the gasket, and the method for producing the gasket are also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
