Booster circuit and voltage generator

A booster circuit to boost a voltage by a plurality of capacitors and a plurality of diodes disposed on each of a plurality of insulating substrates, the booster circuit comprising:

• an input part that is disposed on the insulating substrate to receive a voltage;
• an output part that is disposed on the insulating substrate to output a boosted voltage;
• and
• an L-shaped joint fitting that is a conductive L-shaped joint fitting disposed on the insulating substrate, wherein
• the L-shaped joint fitting includes a first bottom surface portion that is plate-shaped and attached to the insulating substrate, and a first back surface portion that is plate-shaped and extends in a specific direction from the first bottom surface portion,
• in the input part and the output part, a first capacitor among the plurality of capacitors, a first diode among the plurality of diodes, and a connection line that connects the plurality of insulating substrates are electrically connected to the L-shaped joint fitting at a first component connecting portion, and the L-shaped joint fitting is disposed such that a first lead forming portion that is a bent portion of a first lead connected to the first capacitor, a second lead forming portion that is a bent portion of a second lead connected to the first diode, and the first component connecting portion fit within an area of a main surface of the first back surface portion when the main surface of the first back surface portion is viewed from a direction perpendicular to the main surface of the first back surface portion, and
• a portion of the first lead from the first lead forming portion to the first component connecting portion is in contact with the main surface of the first back surface portion.
