Abstract:
A filter chip includes a substrate, a plurality of external terminals formed on the substrate for external connection, and a plurality of passive element forming regions provided in the regions between the plurality of external terminals in plan view when viewed along a direction normal to the surface of the substrate, the plurality of passive element forming regions including at least a resistor forming region where a resistor is formed. The resistor forming region includes a resistive conductive film formed on the substrate with one end and the other end thereof electrically connected to different ones of the external terminals, and a fuse portion integrally formed with the resistive conductive film. The fuse portion is cuttably provided to electrically connect a part of the resistive conductive film to the external terminals, or to electrically separate a part of the resistive conductive film from the external terminals.
