PROBLEM TO BE SOLVED: To obtain an intermediate film for laminated glass which has excellent antiblocking property during storage, excellent handling property when the intermediate film is to be between glass sheets, excellent deaerating property in a preliminary press-sticking process, and which enables an efficient preliminary press-sticking process at a rather low temp. in a wide tamp. range, and to produce a laminated glass. SOLUTION: This intermediate film has 2 to 50 g/cm2 creep elastic modulus at 60 deg.C. Especially, the creep elastic modulus of the intermediate film is <=30 g/cm2 at 60 deg.C, preferably 5 to 20 g/cm2, <=70 g/cm2 at 40 deg.C, preferably 30 to 60 g/cm2, and >=70 g/cm2 at 20 deg.C, preferably 80 to 120 g/cm2. Especially preferably, the intermediate film consists of a polyvinylbutyral resin containing triethylene glycol di(2-ethylhexanoate) or oligoethylene glycol di(2- ethylhexanoate) as a plasticizer.
