A liquid composition for manufacturing electrodes contains a radical polymerizable composition containing an ethylenically unsaturated compound having an oxyethylene group and a polymerization inhibitor, wherein infrared absorption spectra before curing the radical polymerizable composition include a first absorption band in a range of 1640 to 1620 cm−1, a second absorption band in a range of 1430 to 1400 cm−1, and a third absorption band in a range of 820 to 800 cm−1, and the second absorption band has a greater absorption intensity than the third absorption band, and the third absorption band has a greater absorption intensity than the first absorption band, and

wherein the infrared absorption spectra after curing the radical polymerizable composition are substantially free of the first absorption band, the second absorption band, and third absorption band.
