1. An electrical component module attached to a machine section provided behind a service panel arranged on a front side of an outdoor unit of an air conditioner including a refrigerant pipe, the electrical component module comprising:
a main board having a front surface on which an electronic component forming a part of a control circuit that controls the air conditioner is mounted; a power board having a front surface on which an electronic component including a plurality of power devices forming a remaining part of the control circuit is mounted; and a fixed plate on which the main board and the power board are mounted, with a back surface of the main board facing a front surface of the fixed plate, and with a back surface of the power board facing a back surface of the fixed plate, the fixed plate being attached to the machine section, with the front surface of the main board facing a direction toward the service panel, wherein
the outdoor unit includes a cooler attached to a part of the refrigerant pipe so as to face a direction toward the service panel, and the plurality of power devices is vertically arranged on the front surface of the power board and is thermally coupled with the cooler,
the power board has a size in an upward and downward direction that is larger than a size of the plurality of power devices vertically arranged in the upward and downward direction and smaller than a size of the fixed plate in the upward and downward direction, and
the main board has a size in the upward and downward direction that is substantially the same as the size of the power board in the upward and downward direction,
an upper frame component having an elongated shape and that is separate from and attached to both an upper portion of the fixed plate and the machine section; and a lower frame component having an elongated shape and that is separate from and attached to both a lower portion of the fixed plate and the machine section, wherein
the cooler is attached to bridge between the upper frame component and the lower frame component.
