In iron-based superconductors, relationship between superconductivity and the nematic state, where the lattice rotational symmetry is spontaneously broken in the electronic states, has been discussed but unclear. Using spectroscopic-imaging scanning tunneling microscopy, we investigate how the band structure and the superconducting gap evolve in FeSe$_{1-x}$S$_x$, as the sulfur substitution suppresses nematicity that eventually diminishes at the nematic end point (NEP) at $x=0.17$.
