<P>PROBLEM TO BE SOLVED: To provide a sheet with a contact spring and a switch device using it, in which degradation of function is hard to occur even if a separate sheet-like member is pasted on an upper surface part. <P>SOLUTION: A sheet 110 with a contact spring includes a dome-like contact spring 111 for inversion operation under pressure and a holding sheet 112 capable of holding the contact spring 111 on one surface side. The other surface side which is the rear side surface of one surface of the sheet 110 with a contact spring includes first recesses formed parallel to each other by a plurality of numbers in a predetermined work width dimension, and second recesses formed parallel to each other by a plurality of numbers in a predetermined work width dimension, which cross the first recesses. The first recesses are formed with an interval corresponding to the amount of first pitch being smaller than the predetermined work width dimension, and the second recesses are formed with an interval corresponding to the amount of second pitch which is larger than the predetermined work width dimension. <P>COPYRIGHT: (C)2013,JPO&INPIT |
