PROBLEM TO BE SOLVED: To provide a self-retention type reed switch and its manufacturing method using a semi-hard magnetic material which is available with a suitably cost even in a small amount, and of comparatively low cost. SOLUTION: The offset contact point type reed switch is equipped with: a pair of reeds 1a, 1b made of a magnetic material with a contact point parts 3a, 3b at their tips; a movable part 4 sealing the contact point parts 3a, 3b faced with each other by glass 2 and with the movable reed 1b continued to the contact point part 3b of the tip; and a supporting part 5b supporting the movable part 4 through a boundary part with a thickness continuously changed to the movable part 4. The fixed reed 1a is integrally equipped with a contact point part 3a of the tip and the supporting part 5a, the contact point part is made to be contacted with or released from a magnetic field impressed on the reed. The fixed reed 1a forms a rectangular solid and is made of a semi-hard magnetic material. COPYRIGHT: (C)2006,JPO&NCIPI
