PROBLEM TO BE SOLVED: To provide a conductive paste composition consisting of copper as a conductive component capable of achieving stable conductive reliability at low cost by using a specific thermoplastic elastomer as a binder component.SOLUTION: The above described problem is solved by a conductive paste composition containing a structure of the followings (A) to (C). (A) conductive particle containing copper:100 pts.wt. (B) thermoplastic acryl block copolymer having mass average molecular weight of 40,000 to 75,000:5 to 15 pts.wt. (C) organic solvent capable of dissolving or uniformly dispersing the (B) component:1 to 20 pts.wt.SELECTED DRAWING: Figure 1 |
