An experiment has been carried out with the Neutral Detector at the VEPP-2M electron-positron storage ring to search for a possible exotic С state with a mass of about 1.5 GeV. An upper limit has been established on the product of the electron width Г(С^е+е~~) and the probability for decay by the <ртг0 channel for the С state: Г(С->е+е-)В(С-><ртг0) < 70 eV (90% confidence level).
