Claims20
A contact member comprising a surface layer formed on a surface of the contact member, the surface layer comprising a base material comprising a conductor and dispersed particles dispersed in the base material, wherein
- the dispersed particles each comprise a base particle comprising a metal oxide and a coating layer formed on an outer surface of the base particle.
A method for producing a contact member, the method comprising:
- forming a surface layer by immersing a base material comprising a conductor on a surface of the contact member into a solution comprising dispersed particles so as to disperse the dispersed particles in the base material, wherein
- the dispersed particles each comprise a base particle comprising a metal oxide and a coating layer formed on an outer surface of the base particle.
