An object of the present invention is to provide a conductive ink suitable for an inexpensive carbon wiring board having a wide strain detection range, and a carbon wiring board using the conductive ink. The solution is a carbon wiring board having a wiring pattern formed using the conductive ink, which is characterized by comprising: a carbonaceous conductive material (A); Mixture resin (B), above-mentioned binder resin (B) comprises cellulose compound (B1) and poly-N-vinyl compound (B2); And solvent (C), with respect to above-mentioned carbonaceous conductive material (A) 100 Parts by mass include 0.5 to 23 parts by mass of the binder resin (B), and the mass mixing ratio of the cellulose compound (B1) to the poly-N-vinyl compound (B2) is 80:20 to 40:60, and , the above-mentioned solvent (C) contains water (C1). |
