A method for producing a transdermal absorption sheet includes a step of preparing a mold (120) having a plurality of needle-like recessed portions (134) and a step portion (124) which surrounds the recessed portions (134) and is higher than a needle-like recessed portion formed surface (122), and a step of supplying a liquid material (170) from a jetting opening (156) of a filling head (150) to a region surrounded the step portion (124) of the mold (120), in which the filling head (150) includes a head main body (152) having an inner wall surface defining a supply pipe (160A), and the inner wall surface includes a tapered pipe surface defining a tapered pipe (160B) having a diameter gradually increased toward the jetting opening (156) of the head main body (152). Entrainement of bubbles in the liquid material forming the absorption sheet is suppressed.
