PROBLEM TO BE SOLVED: To provide a liquid agent supply device which supplies a plurality of liquid agents while introducing them alternately or successively, and besides, mixing the liquid agents at a proper mixing ratio. SOLUTION: This liquid agent supply device comprises the following components: (1) two exclusive flow paths 25A and 25B connected with the upstream end 10P of a common flow path 10 into which a principal agent and a curing agent are alternately introduced, (2) a gear pump 28 (a displacement pump) installed in each exclusive flow path 25A and 25B, (3) liquid agent regulators 27A and 27B which control so that the primary side pressure of the exclusive flow paths 25A and 25B becomes the same in the respective exclusive flow paths 25A and 25B, and a control valve 13 (a pump control means) which controls the drive of the gear pump 28 so that the primary side pressure and the secondary side pressure becomes the same in accordance with the comparison results obtained by comparing the primary side pressure with the secondary side pressure of the common flow path 10.
