Abstract
Neutrino masses and mixings are explored in superstring-inspired models within the framework of the extended seesaw mechanism. The neutrino mass matrix for the multigeneration case is diagonalized by using the seesaw calculation with the aid of the special structure of the mass matrix. We find that these models predict at least one relatively heavier neutrino. Thus, the possibility of the electron neutrino with a mass of the order of 1 eV can be naturally realized.
