Thin Connector

A connector to be mounted on a board, comprising:

• a housing having an insertion space into which a thin insertion object is inserted;
• a first terminal member configured to be pushed by the thin insertion object to be elastically deformed when the thin insertion object is inserted into the insertion space;
• a second terminal member, having a supported portion supported by the housing, an elastic portion configured to be pushed by the first terminal member to be deformed according to deformation of the first terminal member, and a terminal portion to be soldered to the board, the terminal portion being extended from the supported portion in a direction different form an extending direction of the elastic portion, and;
• a sectional area reducing part, provided in the second terminal member between the supported portion and the terminal portion, and having a sectional area smaller than a sectional area at the terminal portion,
• wherein an insertion state of the thin insertion object is detected based on a change of conduction between the first terminal member and the second terminal member.
