Patent ID: 7364816

Claim:
A laminate type battery, comprising: a substrate; a power generating element which is disposed on the substrate and has at least one single cell made of a positive electrode layer, an electrolyte layer, a negative electrode layer, a first collecting layer and a second collecting layer, the positive electrode layer, the electrolyte layer and the negative electrode layer being sandwiched by the first and second collecting layers from both sides thereof; and an electric circuit member which is disposed on the substrate and has electrode terminals connected to an external device and circuits connecting collecting layers provided in the power generating element and the electrode terminals, wherein the single cell and at least a part of the circuits are formed by stacking: a first layer which includes the first collecting layer, first circuit parts and a first insulating portion, wherein the first circuit parts and the first insulating portion are formed in the periphery of the first layer; a second layer which includes the negative electrode layer, second circuit parts and a second insulating portion, and is stacked on the first layer, wherein the second circuit parts and the second insulating portion are formed in the periphery of the second layer; a third layer which includes the electrolyte layer, third circuit parts and a third insulating portion, and is stacked on the second layer, wherein the third circuit parts and the third insulating portion are formed in the periphery of the third layer; a fourth layer which includes the positive electrode layer, fourth circuit parts and a fourth insulating portion, and is stacked on the third layer, wherein the fourth circuit parts and the fourth insulating portion are formed in the periphery of the fourth layer; and a fifth layer which includes the second collecting layer, fifth circuit parts and a fifth insulating portion, and is stacked on the fourth layer, wherein the fifth circuit parts and the fifth insulating portion are formed in the periphery of the fifth layer, and the circuits are formed by stacking the first to fifth circuit parts so as to electrically connect each other.
