A gel has improved thermal stability and is the hydrosilylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a hydrosilylation catalyst and (D) a phthalocyanine. The (D) phthalocyanine is present in an amount of from about 0.05 to about 30 weight percent based on a total weight of (A) and (B). The gel has a hardness of less than about 1500 grams as measured after heat ageing at 225 DEG C for 1000 hours that is calculated as a weight required to insert a TA-23 probe into the gel to a depth of 3 mm.

Disclosed is a novel deformation-resistant structure of a portable device, capable of reducing an electric failure by decreasing a distortion which occurs in a soldered portion between a printed circuit board of the portable device and an electric part mounted on the board due to a mechanical stress such as drop or pressure. Through slits are formed in positions in a printed wiring plate, which correspond to bosses having prepared holes disposed at the corners of a casing. By inserting screws into the prepared holes through the through slits, the printed circuit board is mounted in the casing. Although the casing is deformed when an external mechanical stress is applied to the casing, the screw and the boss can slide along each of the through slits. Thus, a deformation amount of the printed circuit board is not caused or becomes smaller than that of the casing.
