In a power conversion device according to the present invention, a capacitor module, includes a first capacitor element; a second capacitor element; a positive pole-side bus bar; and a negative pole-side bus bar disposed in a laminated state, in which the positive pole-side bus bar and the negative pole-side bus bar are laminated via an insulating member. The first capacitor element includes a first body portion, a first positive pole-side electrode, and a first negative pole-side electrode. The second capacitor element includes a second body portion, a second positive pole-side electrode, and a second negative pole-side electrode. The first capacitor element is disposed so that the first positive pole-side electrode assumes a position closer to the second negative pole-side electrode than to the second positive pole-side electrode and faces the second negative pole-side electrode; and a laminate portion formed with the positive pole-side bus bar and the negative pole-side bus bar continues up to a point over a space where the first positive pole-side electrode and the second negative pole-side electrode face each other.
