Connector device

A connector device comprising:

• a circuit board;
• a connector;
• and
• a molded resin portion,
• wherein the circuit board includes a conductive path,
• the connector includes:
• a tubular housing made of resin and including a closed side opposite to an open side to which a mating connector is fitted;
• and
• a terminal that protrudes from the inside of the housing to the outside of the housing in an axial direction of the housing and is connected to the conductive path,
• the molded resin portion collectively covers the circuit board, a portion of the terminal located outside the housing, and a portion of the housing,
• a protrusion protrudes in a radial direction of the housing over the entire circumference of the housing in a region adjacent to the closed side so as to be in contact with the molded resin portion, and
• a welded portion is formed on the protrusion and is made of a constituent material of the housing and a constituent material of the molded resin portion welded to each other.
