To provide a wiper deicer for a vehicle which can be easily fitted posteriorly.

A laminated sheet body 12 is made up of an elastic layer 13 that is elastically compressible, and a heating layer 14 that is heated by electrification. The wiper deicer is constituted in such a way that by inserting the laminated sheet body 12 into the gap 5 between the lower part of the windshield 1 and the dashboard 6, the elastic layer 13 is elastically compressed, and the heating layer 14 is closely brought into contact with the windshield 1 by the repulsive force due to the elastic compression.
