NOVELTY - A solar cell sealing material contains ethylene polymer (A) having crystal melting peak temperature of less than 100 degrees C, and olefin polymer (B1) having crystal melting peak temperature of 100 degrees C or more, measured at preset condition. The crystal melting heat amount, needle insertion softening temperature and xylene soluble substance, measured at preset condition, of the sealing material is 1-10 J/g, 75 degrees C or less and 70 %mass or more, respectively.    USE - Sealing material used for solar cell module (claimed) for solar cell used in mobile device, roof and rooftop.    ADVANTAGE - The solar cell sealing material has excellent heat resistance, corrosion resistance and transparency. Easy separation and improved recyclability of the component of the solar cell module produced using the sealing material, are enabled.    DETAILED DESCRIPTION - A solar cell sealing material contains ethylene polymer (A) having crystal melting peak temperature of less than 100 degrees C which is measured at heating rate of 10 degrees C/minute in differential scanning calorimetry, and olefin polymer (B1) having crystal melting peak temperature of 100 degrees C or more, which is measured at heating rate of 10 degrees C/minute with differential scanning calorimetry. The crystal melting heat amount of the sealing material at 100 degrees C measured at heating rate of 10 degrees C/minute in differential scanning calorimetry is 1-10 J/g. The needle insertion softening temperature measured according to JIS K7196 and xylene soluble substance measured according to ASTM 2765-95 of the sealing material is 75 degrees C or less and 70 %mass or more, respectively. INDEPENDENT CLAIMS are included for the following:    (1) solar cell module (100), which is formed using the solar cell sealing material; and    (2) separation of solar cell module, which involves separating the component of the module by heat-processing the solar cell module at 100 degrees C or less.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic sectional view of the solar cell module.
