The layout of cellular phones is limited and it is difficult to reduce the size of cellular phones because a shell is normally attached at the front part of the housing for a conventional connector assembly. In addition, water may permeate deeply between a case and the connector assembly and remain there because a sealing material is disposed at the rear part of a conventional connector assembly. In a connector (1) for an item of electronic equipment, a shell (5) is mounted inside a housing (2), and a sealing material (6) is provided along the outer circumference of the housing (2) at a position close to an end section toward the connection terminal insertion side of the housing (2). Therefore, the length and size of the connector can be reduced, and water can be prevented from permeating deeply between a case and the connector.
