Abstract
A capacitor includes: a capacitor element; a case that houses the capacitor element; and a filler resin that fills an interior of the case. The case includes a case body and a lid. The case body includes a bottom wall, an inner wall having a tube shape, an outer wall having a tube shape and surrounding the inner wall; and a coupler that couples the inner wall to the outer wall. The inner wall rises from a peripheral edge of the bottom wall. The outer wall extends further outward than the bottom wall in a direction from the case body to the lid. The coupler forms a first gap between the inner wall and the outer wall. The bottom wall, the inner wall, the outer wall, and the coupler are integrally formed. The lid closes an opening of the outer wall to form a second gap between the lid and the bottom wall.
