Claim:
1. An aptamer binding to NGF and forming a secondary structure represented by the formula (I): wherein N is one nucleotide selected from the group consisting of A, G, C, U and T, N11-N13, N21-N23, N32-N38 and N42-N48 are the same or different and each is a bond or 1 or 2 nucleotides selected from the group consisting of A, G, C, U and T, N14, N24, N31, N41, N39 and N49 are the same or different and each is one nucleotide selected from the group consisting of A, G, C, U and T, N14 and N24, N31 and N41, and N39 and N49 each form a Watson-Crick base pair, N11-N12-N13-N14 and N21-N22-N23-N24 are nucleotide sequences forming a stem structure of stem 1 in combination, N31-N32-N33-N34-N35-N36-N37-N38-N39 and N41-N42-N43-N44-N45-N46-N47-N48-N49 are nucleotide sequences forming a stem structure of stem 2 in combination, and the final base pair of stem 1 is U-a.
