PROBLEM TO BE SOLVED: To provide a method for producing a polyethylene resin that comprises an ethylene-α-olefin copolymer and the like and is excellent in crosslinking, insulation, and cost, and a solar cell sealing material and a solar cell module including a polyethylene resin produced by the method.SOLUTION: The present invention provides a method for producing a polyethylene resin that comprises an ethylene-α-olefin copolymer, the ethylene-α-olefin copolymer obtained by polymerization using a catalyst system containing the following components (A) and (B). Component (A): a crosslinked metallocene compound having an indenyl skeleton having a substituent. Component (B): a boron compound that reacts with the component (A) to form an ion pair, where the boron compound has a thermal decomposition temperature of less than 200°C at which a weight change occurs in an Natmosphere.SELECTED DRAWING: None 【解決課題】エチレン・α−オレフィン共重合体などからなる、架橋特性、絶縁性、コスト面に優れたポリエチレン樹脂の製造方法、並びにこの方法により製造されるポリエチレン樹脂を用いた太陽電池封止材および太陽電池モジュールを提供すること。【解決手段】エチレン・α−オレフィン共重合体からなるポリエチレン樹脂の製造方法であって、前記エチレン・α−オレフィン共重合体が、下記成分（Ａ）および（Ｂ）を含む触媒系を用いて重合を行うことにより得られることを特徴とする、ポリエチレン樹脂の製造方法。成分（Ａ）：置換基を有するインデニル骨格を有する架橋系メタロセン化合物成分（Ｂ）：成分（Ａ）と反応してイオン対を形成するホウ素化合物であり、Ｎ２雰囲気下における重量変化が起こる熱分解温度が２００℃未満【選択図】なし
