Connector device

A connector device comprising:

• a circuit board;
• a connector attached to the circuit board;
• and a molded resin that covers the entire circuit board and part of the connector and including an attaching portion that is used to attach the connector device to an external device, wherein:
• a housing of the connector contains a resin material and fibrous inorganic fillers, a groove is formed in a region of a surface of the housing that is covered with the molded resin, the groove being formed by removing the resin material with the inorganic fillers remaining, and extending in a direction that intersects a mounting direction in which a counterpart connector is to be mounted to the connector, the groove has a depth and a width in a range from 50 pm to 150 pm inclusive, and the groove is filled with the molded resin, wherein:
• a leading end of a region of the molded resin that covers the housing is arranged in a direction orthogonal to a central axis line of the housing that is parallel to the mounting direction and extends through a center of the connector, and the groove is formed in a region of the housing on a base side of the leading end of the molded resin, the groove being formed in parallel to the leading end.
