A method for constructing and searching an improved Huffman table which is capable of improving the efficiency over an existing Huffman table in a decoding method and apparatus using a Huffman code. The method includes creating an improved Huffman table including an increment of a Huffman code length and the number of times Huffman code lengths repeats; generating a new bit string by extracting bits by the increment of the Huffman code length and adding the extracted bits to the end of a previous bit string; and reading values of corresponding codes by the number of times Huffman code length repeats from the improved Huffman table and determining whether values identical to a value of the new bit string are present. According to the present invention, unnecessary consumption of system resources can be reduced by decreasing the number of times search and comparison routines of Huffman codes are used.
