Electron g-factor in an InAs-inserted-channel In0.53Ga0.47As/In0.52Al0.48As heterostrucrure is studied by measuring angle dependence of magnetotranport properties. The gate voltage dependence of g-factor is obtained from the coincidence method. The obtained g-factor values are surprisingly smaller than the g-factor value of bulk InAs, and it is close to the bare g-factor value of In0.53Ga0.47As. The large change in g-factor is observed by applying the gate voltage. The obtained gate voltage dependence is not simply explained by the energy dependence of g-factor.
