PROBLEM TO BE SOLVED: To provide an electric connection member (an electric connection sheet) of a structure enabling a plurality of connecting points between connection objects to be connected and fixed simply, stably, and in high reliability at the time of mounting. SOLUTION: The electric connection sheet is a mounting sheet 3 having a plurality of conductors arranged in a given pattern in a way exposed to its both sides at given places of a sheet-like laminated body made by jointing a pair of insulators so as to cover both sides of an insulating base material. When the sheet is heated to a given temperature in a state intercalated and pinched between a chip 1 as a connection object and a wiring circuit board 2, each conductor is connected and fixed to each bump 5 of a chip main body 4 (each connecting point of the chip 1) and each land 7 of a board main body 6 (each connecting point of the wiring circuit board 2) at the both sides of the mounting sheet 3. Each insulator making up the mounting sheet 3, here, is composed of a resin material presenting reversible reaction for retaining each conductor in accordance with rise of temperature and bridging reaction for connecting and fixing the object for connection.
