<P>PROBLEM TO BE SOLVED: To provide a dynamic quantity sensor in which lowering of sealability is suppressed by minimizing decrease in seal face smoothness and deformation of a seal face shape. <P>SOLUTION: A dynamic quantity sensor includes a sensor unit for detecting a dynamic quantity of fluid, a terminal connected to the sensor unit, a case for storing the sensor unit and the terminal, a housing with an inlet hole formed, and an O-ring. The case is assembled to the housing so that a portion of the sensor unit exposed from the case is placed in the inlet hole. The inlet hole is closed with the case and the O-ring. The case has a mold member integrally covering the sensor unit and the terminal, a cylindrical cup enveloping an inlet hole side portion of the mold member with the inner wall of the cup, and adhesive mechanically joining the cup and the mold member. The outer wall of the cup contacting the O-ring has smoothness. <P>COPYRIGHT: (C)2012,JPO&INPIT |
