Abstract
A laminate has better handling properties achieved when it is attached to an adherend and which allows the solubility irregularity of the water-soluble material layer to be suppressed. The laminate includes: a 10 to 500 nm thick biodegradable material layer containing an aliphatic polyester and a water-soluble material layer disposed on at least one side of the biodegradable material layer, in which the water-soluble material layer is constituted of a 1 to 20 μm thick first layer containing a water-soluble polymer (a), a 10 μm to 10 mm thick fabric structure containing a water-soluble polymer (b), and a 1 to 20 μm thick second layer containing a water-soluble polymer (c), which are layered in this order from the biodegradable material layer side.

A laminate comprising:
- a 10 to 500 nm thick biodegradable material layer containing an aliphatic polyester and a water-soluble material layer disposed on at least one side of the biodegradable material layer,
- wherein the water-soluble material layer is constituted of a 1 to 20 μm thick first film containing a water-soluble polymer (a), a 10 μm to 10 mm thick fabric structure containing a water-soluble polymer (b), and a 1 to 20 μm thick second film containing a water-soluble polymer (c), which are layered in this order from the biodegradable material layer side.
