The present invention provides a vehicle engine room undercover having excellent high rigidity and heat resistance and comprising a thermoplastic fiber having a shape retention function, and a low-melting point binder at a weight ratio of 4 : 6 to 9 : 1. The low-melting point binder is a low-melting point cis-core fiber. The low-melting point cis-core fiber has a core part, that is a polyester resin, and a sheath layer that is manufactured by copolymerizing an acid component composed of dimethyl terephthalic acid or terephthalic acid and dimethyl adipic acid or adipic acid and a diol component composed of 2-methyl-1,3-propanediol, 1,4-butanediol, and ethylene glycol, and conducting single spinning. Therefore, the undercover has excellent high-rigidity and heat-resistant.
