<P>PROBLEM TO BE SOLVED: To provide a conductive resin composition that can prevent optical information from wrongly being input into or being output from an optical element, by preventing a light incident on the optical element, a light emitted from the optical element, and the like, from being reflected and diffused at a connected part of the optical element and a board. <P>SOLUTION: A conductive resin composition comprises a curing resin (A), a metal-based conductive filler (B), and a black colorant (C). A total blending ratio of the metal-based conductive filler (B) and black colorant (C) in the conductive resin composition is 60 to 90 mass%. When the mass of the black colorant (C) is divided by the mass of the metal-based conductive filler (B), the quotient is 0.01 to 0.15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
