A gas head that at low cost, is capable of inhibiting any deactivation of radical gas and capable of uniformly introducing a raw material gas on a substrate; and a relevant thin-film production apparatus. There is provided gas head (13) comprising reactive gas introduction aperture (30A) for introduction of reactive gas, raw material gas introduction aperture (30B) for introduction of raw material gas and dispersion board (32) disposed opposite to the raw material gas introduction aperture (30B) for dispersing of raw material gas, wherein multiple raw material gas introduction apertures (30B) are disposed so as to surround the periphery of the reactive gas introduction aperture (30A). The reactive gas having been introduced in the reactive gas introduction aperture (30A) is led into the raw material gas introduction aperture (30B) and mixed with the raw material gas having been dispersed by means of the dispersion board (32). The raw material gas introduction apertures (30B), although in multiplicity disposed around the reactive gas introduction aperture (30A), are not needed to be minute holes such as shower holes.
