Electrical contact material

An electrical contact material comprising a silver-containing film, wherein

• the silver-containing film comprises a silver-containing layer containing 50% by mass or more of silver and a plurality of particles made of a non-conductive organic compound, and at least part of each particle is embedded in the silver-containing layer, and
• the non-conductive organic compound contains, in a unit molecular structure, any one or more selected from the group consisting of a fluoro group (—F), a methyl group (—CH3), a carbonyl group (—C(═O)—), an amino group (—NR1R2, wherein R1 and R2 are hydrogen or a hydrocarbon group, and R1 and R2 are the same or different), a hydroxy group (—OH), an ether bond (—O—) and an ester bond (—C(═O)—O—), and the electrical contact material satisfies the following formula (1):
