STRUCTURE FOR CONNECTING LEAD WIRE

A connection portion (2x) of a lead wire (2) is close to a surface of a metal plate (1), held at an accurate position, and held while preventing the wire from being movable, so that the connection portion (2x) is electrically connected to the metal plate (1) reliably and stably. The lead wire (2) connected to the metal plate (1) is held so as not to be disconnected due to vibration or impact. A connection structure of the lead wire (2) includes the metal plate (1), the lead wire (2) connected to the surface of the metal plate (1), and the pair of holding protrusions (3). The holding protrusions protrude from the surface of a lead plate (lA), and sandwich at least two parts of the lead wire (2) to dispose the lead wire (2) at a fixed position. Each of the holding protrusions (3) has a holding gap (3a) sandwiching and holding the press-fitted lead wire (2). A connection space (4) of the lead wire (2) and the metal plate (1) is provided between the holding protrusions (3). The lead wire (2) is held on the surface of the metal plate (1) with the holding protrusions (3). The lead wire (2) is connected to the surface of the metal plate (1) in the connection space (4).
