Abstract:
A positioner (1) includes: a displacement amount detector (11) that outputs a pair of detection signals; an interconnection board (15) that includes an interconnection layer (L1) which is disposed between two insulating layers (100, 101) and has a pair of signal interconnections (22, 23), having the pair of detection signals supplied thereto, formed therein; a circuit board (20) on which an electronic circuit (12) generating a control signal for controlling a valve opening of the regulating valve on the basis of the pair of detection signals is formed; and a housing (10). The interconnection board is bonded to the housing by a conductive adhesive member (30) in at least a portion of a surface of any one of the insulating layers, and the adhesive member has a measured value of hardness, which is obtained by a type D durometer after hardening, being in a range of equal to or greater than D20 and equal to or less than D90.
