The invention provides a solid-state battery which can prevent short circuit and can be installed at a high density even when the solid-state battery is installed in a mixed manner with a very small component. This solid-state battery is provided with: a battery main body including a positive electrode layer and a negative electrode layer laminated with a solid electrolyte layer interposed therebetween, the battery main body having a first end surface and a second end surface facing each other, and a peripheral surface disposed between the first end surface and the second end surface; a first external electrode provided on the first end surface; a second external electrode provided on the second end surface; and a protective layer covering a peripheral surface of the battery body, the solid-state battery having a first main surface and a second main surface facing each other in a stacking direction of the positive electrode layer and the negative electrode layer. The first external electrode covers the first
