Abstract
For electronic circuit members including a high density fine pattern electrode and a flexible printed circuit, a reinforced connecting part includes a reinforcing fastener which is a substantially cylindrical section shaped element having edges defining an axial slit clamping the circuit members. The reinforcing fastener is formed of an alloy having both superelastic and shape memory characteristics at a temperature above the Martensite transformation temperature of the alloy. The alloy is brought to a temperature above the Martensite transformation temperature after the slit is opened at a temperature below the Martensite temperature of the alloy and the electronic circuit members are attached via the slit. The circuit members can thus be fastened with a substantially constant force over time due to the superelastic and shape memory characteristics of the alloy.
