To provide a coating method where a liquid is applied while restraining the remaining of bubbles to a base material with grooves formed on a surface.SOLUTION: In a coating method, a liquid is applied on the surface 8 of a base material 7 with grooves 9 formed on the surface 8 by a coater 12 having a slit 42 long in one direction and capable of discharging the liquid from the opening 42a of the slit 42. The method includes a coating step to discharge the liquid from the opening 42a to the surface 8 while relatively moving the base material 7 and the coater 12 in a state where the opening 42a and the surface 8 are close. In the coating step, the liquid is discharged to the base material 7 from the coater 12 while relatively moving the base material 7 and the coater 12 in a state where the longitudinal direction of the opening 42a projected when projecting the opening 42a on the surface 8 and the longitudinal direction of the grooves 9 are inclined.SELECTED DRAWING: Figure 2 【課題】表面に溝が形成されている基材に対して、気泡の残存を抑制して液を塗布する。【解決手段】一方向に長いスリット４２を備え当該スリット４２の開口４２ａから液を吐出可能である塗布器１２によって、表面８に溝９が設けられている基材７の当該表面８に液を塗布する方法である。前記開口４２ａと前記表面８とが接近した状態で、基材７と塗布器１２とを相対的に移動させながら、当該開口４２ａから液を当該表面８に対して吐出させる塗布工程を含む。塗布工程では、前記開口４２ａを前記表面８に投影した場合に当該投影した開口４２ａの長手方向と、前記溝９の長手方向とが傾斜する状態で、前記基材７と前記塗布器１２とを相対的に移動させながら、当該塗布器１２から液を当該基材７に対して吐出させる。【選択図】 図２
