All-solid-state electrode body and electrochemical cell

An all-solid-state electrode body, comprising:

• a stacked body in which a positive electrode connection layer and a negative electrode connection layer are alternately stacked in a first direction via a solid electrolyte;
• a positive electrode via which extends on an inner side of the stacked body in a first direction through a negative electrode escape portion that is formed in the negative electrode connection layer, and connects a plurality of the positive electrode connection layers adjacent to each other in the first direction;
• a negative electrode via which extends on an inner side of the stacked body in the first direction through a positive electrode escape portion that is formed in the positive electrode connection layer, and connects a plurality of the negative electrode connection layers adjacent to each other in the first direction;
• a positive electrode current collector layer which is exposed on a first surface that faces one side of the first direction in the stacked body, and is connected to the positive electrode connection layer via the positive electrode via;
• and
• a negative electrode current collector layer which is exposed on the first surface in the stacked body, and is connected to the negative electrode connection layer via the negative electrode via.
