摘要： The present invention provides an intermediate laminate that is suitably used in laminates such as laminated glass, can be provided with various functions by a simple method, has a high degree of freedom of design of the functions to be imparted, and has good transmission visibility, and a laminate comprising the same. The intermediate laminate (5A) of the present invention comprises a first adhesive layer (11) and a first cross-linked cured resin layer (12) laminated directly with no other layer interposed therebetween, and the first adhesive layer (11) comprises a polyvinyl acetal resin and/or an ionomer resin. The first cross-linked cured resin layer (12) preferably has a fine concave and convex pattern on a surface on the side opposite to the first adhesive layer (11) side. A laminate (6A) comprises the intermediate laminate (5A) and a pair of translucent base materials (21 and 22) holding the intermediate laminate (5A) therebetween.
