1. A connector comprising:
a terminal fitting; and
a housing holding the terminal fitting,
wherein the housing comprises:
a first resin molded body in which at least a part of the terminal fitting is embedded, the first resin molded body being made of a first material; and
a second resin molded body in which at least a part of the first resin molded body is embedded, the second resin molded body being made of a second material,
wherein the first material has a linear thermal expansion coefficient smaller than that of the second material,
wherein the connector is connectable to a counterpart connector comprising a counterpart terminal,
wherein the terminal fitting includes a contact portion shaped in a form of a hollow tube having a first open end and a second open end, the contact portion being configured to contact the counterpart terminal when the connector is connected to the counterpart connector, and
wherein the first resin molded body includes:
a shaft-shaped portion disposed inside the hollow tube of the contact portion, the shaft-shaped portion having a first end and a second end, the second end being closer to the second open end of the contact portion than the first end;
a first end portion connected to the first end of the shaft-shaped portion and covering the first open end of the contact portion; and
a second end portion connected to the second end of the shaft-shaped portion and covering the second open end of the contact portion.
