A valve main unit, in which a high pressure valve is to be provided, includes a channel for hydrogen gas. An internal surface of the channel is constituted by an oxidation layer formed by performing anodizing on an aluminum-based alloy. The oxidation layer of the channel is formed by performing the anodizing under a condition in which the oxidation layer with a thickness of 8 μm or less is formed at an external surface of the valve main unit, the external surface having an opening communicating with the channel.
