Patent ID: 7927386

Claim:
A method for manufacturing a battery pack, comprising: providing a rechargeable battery having a sealing plate on a sealing plate side and a bottom face: connecting a circuit substrate having an external terminal to the rechargeable battery by a connecting member; said circuit substrate having a first substrate side surface on which said external terminal is disposed and having a second substrate side surface opposite said first substrate side surface; arranging the circuit substrate such that said second substrate side surface of the circuit substrate faces the sealing plate of the rechargeable battery and defines a gap therebetween thereby forming an object to be resin packed; placing the object to be resin packed inside a die such that the rechargeable battery and the circuit substrate are in predetermined positions; filling the gap between the rechargeable battery and the circuit substrate with resin thereby forming an intermediate product by integrally uniting the rechargeable battery and the circuit substrate; and forming an outer covering such that at least the external terminal of the intermediate product is exposed to the outside.
