A battery lead plate assembly comprises a one-piece integral structure for connecting together a circuit block and a battery of an electronic timepiece. The assembly comprises a casing composed of electrically insulative material and having a slotted arm portion, a lead plate element composed of electrically conductive material and having an end portion inserted into the slot, and an insulating plate composed of electrically insulative material and having an end portion inserted into the slot - all three parts being thermo compression bonded into a one-piece integral structure. The lead plate element is configured so as to contact and make electrical connection between the circuit block and the battery and the insulating plate is configured so as to extend along the side of the lead plate element opposite the battery for electrically insulating the lead plate element from other parts of the timepiece.
