Provided is a technique for easily increasing the capacitance of an average installation area. According to one embodiment, a capacitor (1) includes a conductive substrate, a conductive layer, a dielectric layer, and first and second external electrodes. The conductive substrate has a first main surface provided with recess(s), a second main surface, and an end face extending between edges of thefirst and second main surfaces. The conductive layer covers the first main surface and side walls and bottom surfaces of the recess(s). The dielectric layer is interposed between the conductive substrate and the conductive layer. The first external electrode (70c) includes a first electrode portion (70c3) facing the end face and is electrically connected to the conductive layer. The second external electrode (70d) includes a second electrode portion (70d3) facing the end face and is electrically connected to the conductive substrate. 提供能够容易地增大平均设置面积的电容的技术。实施方式的电容器(1)具备：导电基板，具有第1主面、第2主面及从上述第1主面的边缘一直延伸到上述第2主面的边缘为止的端面，在上
