WA chemical solution supply apparatus (1) includes a container (10) and a chemical solution supply implement (20) that can, in a state of being connected to a mouth portion (14), switch over a state where the container (10) is sealed and a state where a chemical solution in a storage portion (12) is allowed to be supplied to the outside of the container (10). The chemical solution supply implement (20) has a base (30) and a supply body (50). The base (30) has a retaining portion (40), a pressing portion (42), and a restricting portion (34) that restricts displacement of the supply body (50) with coming into contact with the supply body (50) when the supply body (50) is pressed against pressing force of the pressing portion (42). The supply body (50) moves away from the retaining portion (40), thereby forming a supply flow passage, and comes into contact with the retaining portion (40), thereby blocking the supply flow passage. 23
