PROBLEM TO BE SOLVED: To provide a sash which facilitates the removal of water, dust, etc. while securing the beauty of a top surface of a sill. SOLUTION: Inner and outer sliding screens 2 and 3, and a wire screen 4 are housed in a frame body 1 in which a head, the sill, and right and left jambs are framed in a square shape; the top surface of the sill 11 is formed in such a shape that an outdoor side is lower than an indoor one; a rising piece 30, and inner and outer rails 31 and 32 are formed in an orthostatic shape; a lower wire screen frame 33, which is equipped with a wire screen frame-elongated portion 33a, is formed on the outdoor surface of the outer rail; a resin sill 35, the top surface of which is positioned above that of the sill, is mounted between the rising piece and the inner rail; a between-rails cover material 36, the top surface of which is positioned above that of the sill, is mounted between the inner and outer rails; and the top surface of the resin sill, that of the between-rails cover material, and that of the wire screen frame-elongated portion constitute an apparent surface 14 with approximately the same height from the indoor side of the sill to the outdoor side thereof.
