PROBLEM TO BE SOLVED: To provide a simple sash structure which can cover the indoor side of a mullion and that of a transom, and which can be selectively provided with a wire screen. SOLUTION: In a frame body 1, a plurality of sections are formed by vertically and horizontally providing partition materials 13 and 14 in a frame in which a head, a sill, and right and left jambs are framed. A screen 2 is housed in each of the sections. In the partition material 13, rising pieces 43 are formed on inner peripheral surfaces on both sides, facing an outer peripheral surface of the screen 2, respectively. In the rising piece 43, an airtight material 44 abutting on the screen 2 is provided along a longitudinal direction. An inner resin frame 30 is attached in such a manner as to cover indoor side surfaces of the rising pieces 43 on both sides and an indoor side with respect to them. A rising piece covering portion 31 for covering the indoor side surface of the rising piece 43, and an indoor side portion 32 for covering the indoor side surface of the partition material 13 are formed in the inner resin frame 30. The indoor side portion 32 faces the rising piece covering portion 31, and a recessed storage groove 33 is formed between the indoor side portion 32 and the rising piece covering portion 31, so that the expansion wire screen 5 can be housed in the storage groove 33.
