The present invention relates to a PCR primer facilitating hot-start PCR by suppressing non-specific amplification at room temperature and at the same time capable of reducing significantly non-specific amplification by dominating the amplification of the PCR product rather than the amplification of the original template from the third PCR cycle, more precisely a PCR primer prepared by additionally inserting the reverse-complementary sequence to a certain region starting from the 5'-start site of the 5&#x2032;-terminus of the original primer which is composed of priming sequence to anneal to a PCR template into the 5&#x2032;-terminus of the original primer and a PCR method using the same. The primer of the present invention has a original primer sequence composed of priming sequence to anneal to a PCR template and an additional reverse-complementary sequence, which inserted into the 5&#x2032;-terminus of the original primer, to a certain region starting from the 5&#x2032;-start site of the 5&#x2032;-terminus of the original primer sequence, suggesting that a template-specific sequence and its reverse-complementary sequence are included in the same primer. The present invention can improve PCR specificity by reducing non-specific amplification.
