A heat source apparatus includes a refrigerant circuit, a refrigerant container, a connection part, a communication pipe, and a protective member. The refrigerant circuit includes a compressor and a heat exchanger. The refrigerant container is connected to the refrigerant circuit. The refrigerant container is filled with a flammable refrigerant. The connection part is connected to the refrigerant container. The communication pipe connects the connection part to the refrigerant circuit. The protective member protects the connection part.

An electric component box that achieves both safety and cooling inside the electric component box is provided. An electric component box that is mounted in a heat pump unit and includes electric components inside includes an inner box and an outer box. The inner box accommodates a printed circuit board on which the electric components are mounted, and has a sealed structure. The outer box covers the inner box. In the electric component box, since the inflow of gas into the inner box is suppressed, for example, the contact of air containing a pollutant or flammable gas with electrodes of the electric components is also suppressed.
