A main object of the present invention is to provide an encapsulant for a photovoltaic module, which may inhibit the encapsulant from clouding when a hot spot phenomenon is caused. To attain the object, the invention provides an encapsulant for a photovoltaic module comprising: a resin for an encapsulant containing a silane-modified resin obtained by polymerizing an ethylenically unsaturated silane compound and polyethylene for polymerization; and a master batch containing a UV-absorbent, a light stabilizer, a thermal stabilizer and polyethylene for use in a master batch, characterized in that the polyethylene for polymerization and the polyethylene for use in a master batch are metallocene based linear low density polyethylene having a density in the range of 0.895 g/cm 3 to 0.910 g/cm 3 . |
