To provide a multilayer channel member with high accuracy capable of improving fluid measurement accuracy and an ultrasonic fluid meter using the multilayer channel member.
A support portion 11b of a partition plate 11 is inserted into an inserting portion 19a of an insert hole 19 of side plates 12, 13 and then slid to a fixing portion 19a at the side, thereby the partition plate 11 is fixed to the side plates 12, 13 and precisely fixed to a fixing portion 20b. That is, the support portion 11b of the partition plate 11 can be surely easily inserted by the inserting portion 19a of the side plates 12, 13 and the support portion 11b can be surely fixed with high accuracy by sliding to the fixing portion 19b.
