Conductive film, and transducer and flexible wiring board using the same
摘要:
To provide a conductive film that is flexible, extendable and contractible, and for which the electrical resistance hardly increases even when the conductive film is extended. The conductive film contains an elastomer and metallic filler particles, and satisfies a condition (A) [an average value of reference numbers is 0.8 (1/μm) or more, or the metallic filler particles include flake-like metallic filler particles having a thickness of 1 μm or less and an aspect ratio of 26 or more and the average value of the reference numbers is 0.4 (1/μm) or more] and a condition (B) [a number of unit areas for which an area percentage of the elastomer is 60% or more is 20 or more], the condition (A) being a conductivity indicator and the condition (B) being a flexibility indicator.
