Abstract: The present invention provides a squeezable, cross-linked, grease-like electromagnetic wave absorber which comprises a cross-linked silicone gel preferably having a consistency of 50 to 200 (determined in accordance with JIS K 2220 with a ¼ cone), dispersed with an electromagnetic wave absorbing filler preferably comprising an electromagnetic wave absorbing agent and flame retardant; shows self-shape-retaining nature in spite of its fluidity; contains the filler at 200 to 800 parts by mass per 100 parts by mass of the cross-linked silicone gel; is excellent in electromagnetic wave absorbing capability, thermal conductivity and flame retardancy; has limited temperature dependency; is squeezable; and is applicable to a gap and site to be formed into a thin film thereon, to which a sheet product is essentially inapplicable.

Abstract: An electromagnetic wave absorber comprising (a) soft ferrite having its surface treated with a silane compound having no functional group, (c) magnetite and (d) silicone, or comprising (a) soft ferrite having its surface treated with a silane compound having no functional group, (b) flat, soft magnetic metal powder, (c) magnetite and (d) silicone, which electromagnetic wave absorber excels in electromagnetic wave absorption, heat conduction and flame resistance, exhibiting less temperature dependence, and which electromagnetic wave absorber is soft, excelling in adhesion strength and further excelling in high resistance high insulation properties and in energy conversion efficiency being stable in MHz to 10 GHz broadband frequency.

Abstract: A grip using a gel substance capable of preserving its own shape is provided in a grip portion of a barrel of a writing implement. An outer coat for covering the grip portion of the barrel 1 is provided. The gel substance is located between the outer coat and the barrel, and comes in direct contact with the barrel. A centering member for positioning the outer coat coaxially with the barrel is provided between the outer coat and the barrel. The centering member is provided with an opening for allowing a space between the outer coat and the barrel to communicate with the outside of the space. The gel substance is formed by injecting a sol substance, which is a raw material, through the opening and by crosslinking the sol substance under a predetermined condition.
