Die coating apparatus, die coating method, and adhesive sheet and foamed sheet

A die coating apparatus, which comprises a die comprising an upstream-side bar and a downstream side-bar aligned with each other along a direction of transportation of a band-shaped support continuously transported by a backup roll so as to form a pocket for storing a coating solution and a slit serving as a feed-out path of the coating solution, said slit having an outlet for feeding out the coating solution stored in the pocket of the die therefrom to thereby coat the coating solution on the band-shaped support,

• wherein the downstream-side bar has a lip having a divergent cross-sectional shape continuous in the direction of a width of the downstream-side bar, and an inclination angle θ of a side end part on the most downstream side of the lip of the downstream-side bar is within the range of 20° to 80° and wherein a height of the tip part of a lip of the upstream-side bar is larger than a height of a tip part of the lip of the downstream-side bar by 0.3 mm to 3 mm.
