Abstract

A shade member and a window blind including multiple such shade members are provided. The shade member is made by welding a first shade element, a second shade element, and a third shade element together. The second shade element is situated on a first region of the first shade element, while the first shade element and the second shade element are unified by longitudinally overlapping and ultrasonic welding. The third shade element is situated on a second region of the first shade element, while the first shade element and the third shade element are unified by longitudinally overlapping and ultrasonic welding. Such a structure allows the shade member to easily include distinct portions made of different materials, so that the window blind including such shade members can provide a variety of appearance designs and texture combinations while lowering the production cost and increasing the production efficiency.
