<P>PROBLEM TO BE SOLVED: To provide a flow rate control valve reduced in costs and easy to be manufactured. Ž<P>SOLUTION: This flow rate control valve includes: a valve element 5 provided between an inlet chamber 2 and an outlet chamber 3 to open/close communication between both the chambers; and a valve spring 7 for bringing the valve element into pressure-contact with a vale seat 6. One end of a swelling body 15 formed from a synthetic resin having a high coefficient of linear expansion is fixed to a swelling body cover 13, and the other end of the swelling body to be displaced by a change of the peripheral temperature is arranged freely to move relative to the swelling body cover, and the valve element is separated from a valve seat, resisting a valve spring, with the movement of the other end of the swelling body, and both the chambers are communicated with each other to control a flow rate to a linear shape in response to a change of the peripheral temperature.
