NOVELTY - A resin composition contains (in parts mass) polyphenylene ether (57-94), hydrogenated block copolymer (3-30) and organophosphorus flame retardant (3-30). The hydrogenated block copolymer is obtained by hydrogenating block copolymer containing polystyrene block and conjugated diene compound polymer block, and has weight average molecular weight of 100000-500000. The value of peak height of the loss tangent (tan-( delta )) of the hydrogenated block copolymer is 0.075-0.120, which is calculated from dynamic-viscoelasticity spectrum at frequency of 10 Hz.    USE - Resin composition is used for molded product e.g. solar cell modular component, connector and connection box (all claimed). Uses include but are not limited to electrical/electronic components for television, business machine components, motor-vehicle component, building materials and industrial products.    ADVANTAGE - The resin composition has excellent moldability, heat resistance, flame retardance, long-term thermal aging resistance and impact resistance.    DETAILED DESCRIPTION - A resin composition contains (in parts mass) polyphenylene ether (57-94), hydrogenated block copolymer (3-30) and organophosphorus flame retardant (3-30). The hydrogenated block copolymer is obtained by hydrogenating block copolymer containing polystyrene block and conjugated diene compound polymer block, and has weight average molecular weight of 100000-500000. The value of peak height of the loss tangent (tan-( delta )) of the hydrogenated block copolymer is 0.075-0.120, which is calculated from dynamic-viscoelasticity spectrum at frequency of 10 Hz using relation of formula: Peak height of the loss tangent (tan-( delta )) of hydrogenated block copolymer=(height of the peak in chart)/(content rate of the hydrogenated block copolymer in a resin composition (in %mass)). INDEPENDENT CLAIMS are included for the following:    (1) manufacture of resin composition;    (2) molded product;    (3) solar cell modular component;    (4) connector; and    (5) connection box.
