A sheet-shaped flexible electrode includes a thermoplastic elastomer including a styrene-based thermoplastic elastomer or including a styrene-based thermoplastic elastomer and an olefin-based thermoplastic elastomer, and a conductive material containing carbon black, and has a thickness of 50 μm or more and 500 μm or less. The melt viscosity of the thermoplastic elastomer at 200° C. in a low shear region with a shear rate of 60 s−1 or more and 200 s−1 or less is 100 Pa·s or more and 800 Pa·s or less, and is four times or less the melt viscosity of the thermoplastic elastomer at the same temperature in a high shear region with a shear rate of 1000 s−1 or more and 1220 s−1 or less. An amount of DBP absorbed by the carbon black is 300 cm3/100 g or more.
