PROBLEM TO BE SOLVED: To provide a contact sheet that can respond to dispersion of height and size of ball terminal and has no damage of a leading end and that has a shorter passing distance of current and is of exchangeable structure. SOLUTION: A contact sheet 5 is used in a socket for connecting integrated circuit 7 provided with a spherical terminal 6 and a board 8, and a contact spring 3 is made conductive material and includes more than two cantilevers 9 adhered or held to be fixed to one end of a sheet 1. Each of the cantilever 9 has lower base portions 10 and spherical shape of holding portions 11, and the lower base portions 10 include straight or plane portion adjacent to the fixing portion to the sheet 1, and the spherical shape of the holding portions 11 are bent vertically to direct one of two openings which are passing through the other end of the support pieces 9.
