A connector is mateable with a mating connector along an up-down direction. The connector comprises a contact, a holding member and two reinforcing members. The holding member has an accommodation portion and an island-like portion. The island-like portion has two end portions in a first horizontal direction perpendicular to the up-down direction. The reinforcing members are positioned at the two end portions, respectively. Each of the reinforcing members has a guard portion and a supporter. The guard portion of each of the reinforcing members guards the corresponding end portion of the island-like portion. The guard portion has an upper surface, an embedded portion and an exposed coupling portion. The upper surface is exposed upward from the island-like portion in the up-down direction. The embedded portion is embedded into the island-like portion. The exposed coupling portion couples the upper surface and the embedded portion with each other.
