PROBLEM TO BE SOLVED: To provide a microrelay by which reliability of contact between a traveling contact and a fixed contact is improved. SOLUTION: The microrelay includes a base board 1 wherein a holder to hold an electromagnetic device 2 is formed and the fixed contact 14 is provided at one surface side of a thickness direction, an armature block 3 having a frame 31 fastened to one surface side of the base board 1, an armature 30 which is arranged inside the frame 31 supported by the frame 31 in a rocking manner through a support spring 32, and is driven by the electromagnetic device 2, and a base 34 for the traveling contact which is supported by the armature 30 through a contact pressure spring 35, and a cover 4 of which periphery is fastened to the frame 31 at an opposite side to the base board 1 in the armature block 3. The traveling contact 39 which comes into contact with and moves away from a pair of the fixed contacts 14 is provided at the base 34 for the traveling contact. An opposite face to the fixed contact 14 in the traveling contact 39 is formed on a convex curved surface projected to a side of the fixed contact 14. COPYRIGHT: (C)2005,JPO&NCIPI
