Abstract: A composition of the present invention includes: a styrene-based elastomer; a paraffin-based process oil; an olefin resin; a crosslinking agent including an organic peroxide; a crosslinking aid; an antioxidant; and a surface-treated filler obtained by surface treating particles formed from magnesium hydroxide with a higher fatty acid. The paraffin-based process oil has a kinematic viscosity at 40° C. of 300 mm2/s or greater. Furthermore, from 405 to 485 parts by mass of the paraffin-based process oil, from 9 to 13 parts by mass of the olefin resin, from 5 to 7 parts by mass of the crosslinking agent, from 13 to 15 parts by mass of the crosslinking aid, from 3 to 4 parts by mass of the antioxidant, and from 15 to 25 parts by mass of the surface-treated filler are respectively blended per 100 parts by mass of the styrene-based elastomer.

Abstract: A contact includes a base portion fixable to a first member, a contact portion configured to make contact with a second member, and a spring portion configured to displaceably support the contact portion. The base portion, the contact portion, and the spring portion are integrally formed with a thin plate made of metal. The contact portion includes a flat plate portion extending in a flat plate shape from one end of a bent portion, and a protrusion protruding toward the second member is provided on the flat plate portion. The protrusion is provided at a location separated from a boundary between the contact portion and the spring portion by greater than or equal to 0.9 mm toward the contact portion.
