Claim 0:
1. A binder composition for an electrochemical device comprising: a polymer including a nitrile group-containing monomer unit and an alkylene structural unit; and a group 13 element, wherein
the group 13 element is aluminum,
the concentration of the group 13 element is not less than 1 ppm and not more than 40 ppm, and

when an iodine value of the polymer is taken to be I, in units of g/100 g, and concentration of the group 13 element is taken to be M, in units of ppm, a relationship formula:

0.1≤M/I≤150, is satisfied.
