Abstract:
1. A flow path member comprising: a liquid flow path through which a liquid flows; a groove-shaped flow path configuring a portion of the liquid flow path and a communication path communicating with the groove-shaped flow path; a flexible member which forms a pressure chamber in the groove-shaped flow path by sealing an opening of the groove-shaped flow path and is flexibly deformed by pressure variation inside the pressure chamber; a valve body which has a shaft section inserted through the communication path and a valve main body provided on the shaft section, is able to enter a valve closing state in which the valve main body closes the communication path and a valve opening state in which the valve main body is separated from the communication path, and is biased to be in the valve closing state; and a pressure receiving member which is displaced by receiving a pressing force from the flexible member due to displacement of the flexible member to the pressure chamber side and then is able to press the shaft section in a direction where the valve body enters the valve opening state, wherein the valve body is able to rotate around the shaft center, the valve main body is provided with a seal member, which comes in contact with an opening edge of the communication path, and the seal member is formed in a shape of an annulus of which a distance from the shaft section is not constant.
