Abstract

In the present invention, a non-combustion-type aspirator (100) comprises: a power source BAT; a heater connector Cn; a step-up DC / DC converter (9); a receptacle mounting substrate (162) in which the step-up DC / DC converter (9) is disposed on a secondary surface (162b); output capacitors C8-C12; a power ground PGND provided inside the receptacle mounting substrate (162) and connected to the output capacitors C8-C12; a signal ground AGND insulated from the power ground PGND inside the receptacle mounting substrate (162) and connected to a feedback terminal FB of the step-up DC / DC converter (9); and a common ground CGND. On the secondary surface (162b) of the receptacle mounting substrate (162), no electronic components are provided in a common ground projection area (167) that overlaps the common ground CGND.
