1. A flow passage switching valve for a fluid circulation circuit that is for a fluid circulating, the flow passage switching valve comprising:
a body forming therein a fluid passage for the fluid flowing therethrough; and
a switcher configured to switch a passage configuration of the fluid passage, wherein
the body includes a first inlet for the fluid flowing into the body, a second inlet for the fluid flowing into the body, and outlets for the fluid having flowed into the body and flowing out of the body,
the outlets include a first outlet for the fluid having flowed in from the first inlet and flowing out of the body,
the switcher is configured such that the passage configuration is switchable to a state in which the fluid having flowed in from the first inlet flows out of either one of the outlets,
the switcher is configured such that the passage configuration is switchable to a state in which the fluid having flowed in from the second inlet flows out of either one of the outlets, and
the fluid circulation circuit is configured such that a first pressure of the fluid flowing into the first inlet is higher than a second pressure of the fluid flowing into the second inlet.
