    摘要： An object is to prevent deterioration of the electrochemical reaction performance of an electrochemical reaction block as a whole.
    An electrochemical reaction cell stack includes an electrochemical reaction block including three or more electrochemical reaction units arranged in a first direction; a first heat-absorbing member which is disposed on one side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block; and a second heat-absorbing member which is disposed on the other side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block. An upstream electrochemical reaction unit is disposed between the first heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the first heat-absorbing member, and an upstream electrochemical reaction unit is disposed between the second heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the second heat-absorbing member.

    摘要： A pressure sensor of the present invention includes a housing extending along an axial line, a diaphragm fixed to a front-end side of the housing, a piezoelectric unit disposed in a hole in the housing and including a piezoelectric element, a transmission member that transmits deformation of the diaphragm to the piezoelectric unit, and a guide member having a through hole extending along the axial line and surrounding the piezoelectric unit in the through hole. (SL/AL) ≦ 0.26 is satisfied in the cross section perpendicular to the axial line passing through the piezoelectric element, where SL is the maximum value of the distance in the radial direction between the center of the through hole and the center of the piezoelectric element and AL is the maximum value of the distance in the radial direction between the outside surface of the piezoelectric element and the center of the through hole.
