The invention discloses a semi-aromatic polyamide resin, and the semi-aromatic polyamide resin comprises the following components in mole fraction: 1) 48.9-51 mol% of decamethylene diamine, 2) 48.9-51 mol% of terephthalic acid, 3) hyperbranched polyethylenimine, wherein the content of the hyperbranched polyethylenimine is 0.001-0.1% of the total mole of the decamethylene diamine and the terephthalic acid and the molecular weight is less than or equal to 2000. The resin structure disclosed by the invention contains a hyperbranched structure unit, so that the liquidity of the semi-aromatic polyamide resin is improved, and the resin is easy to process; after the decamethylene diamine and the terephthalic acid are subjected to salifying, hyperbranched polyethylenimine is added, geometric salifying of the decamethylene diamine and the terephthalic acid is ensured, PA10T prepolymer is furthermore formed, the final resin structure is stable, and the product performance is uniform. 本发明公开了种半芳香族聚酰胺树脂，按摩尔分数计，包含如下组分的重复单元
