A transmission screen having a writable and erasable surface for one side is provided. This transmission screen is constructed so that the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 70 to 135%, the transmission screen as a whole should have a haze (JIS K7136:2000) of 80% or more, and the surface opposite to the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 10% or less. With this transmission screen, writing with a marker for white boards and erasing can be easily done while seeing images projected on the transmission screen, and the images from a projector do not become hard to see due to projection of the images on the body of a writer.
