We propose a quark-lepton model via leptoquarks and modular symmetry. Since the neutrino mass is induced at one-loop level mediated by down quarks as well as leptoquarks, we have to explain lepton and quark masses and mixings with a single modulus 
. Here, we find predictions for lepton and quark sectors with unified modulus , and show several constraints originating from leptoquarks.
