Abstract
Provided is a method for producing a granular powder-containing sheet containing a granular powder in separated container rooms between two sheet materials. After the container rooms are formed in a first sheet material, the first sheet material is transported on the circumferential surface of an anvil roller. In the process of transportation, the granular powder that is fed from a granular powder feeding hopper through a feeding passage is received in the container rooms. Thereafter, the container rooms are covered with a second sheet material, and the two sheet materials are joined to each other on the peripheries of the container rooms.
