<p>PROBLEM TO BE SOLVED: To provide an impregnation device and an impregnation method which continuously vacuum-impregnate pores in a porous body with an impregnation liquid by using a simple structure.SOLUTION: An impregnation device includes: a liquid storage tank (2) in which an impregnation liquid (20) is stored; a hollow tube (3) disposed in the liquid storage tank (2); a vacuum pump (5) which forms a vacuum part (31) at the other end side of the hollow tube (3); and a transport mechanism (6) which moves a porous body (40) in the impregnation liquid (20) drawn into the hollow tube (3). A degree of vacuum of the vacuum part (31) is maintained in a predetermined range.</p> |
