A passive component includes an inorganic substrate having a first main surface and a second main surface, which are opposed to each other, and contains a semiconductor material; and a passive element portion on the first main surface of the inorganic substrate so as to be in contact with the first main surface. When a cross section in a plane that passes through a center of gravity in a whole of the first main surface and is orthogonal to the first main surface is defined as a first cross section, in the first cross section, the inorganic substrate has a first side surface and a second side surface, which are connected with the first main surface and opposed to each other, and each of line roughness of the first side surface and line roughness of the second side surface is larger than line roughness of the first main surface.
