Abstract:
1. An electronic circuit device comprising, an electronic circuit element, a substrate including a front surface on which the electronic circuit element is mounted and a reverse surface opposite to the front surface in a thickness direction of the substrate, an electrically conductive terminal member electrically connected to the electronic circuit element, a lead frame extending perpendicular to the thickness direction to face the reverse surface in the thickness direction, and a sealing resin covering at least partially the electronic circuit element, substrate and lead frame while at least a part of the electrically conductive terminal member is prevented from being covered by the sealing resin to protrude from the sealing resin in a transverse direction perpendicular to the thickness direction and parallel to a longitudinal direction of the at least a part of the electrically conductive terminal member, wherein the substrate extends to project outward with respect to an end of the lead frame in the transverse direction perpendicular to the thickness direction while the end of the lead frame is covered by the sealing resin in a cross sectional view taken along an imaginary plane passing the substrate and lead frame and extending parallel to the thickness direction, the lead frame is formed in one-piece, a part of the lead frame in one-piece is prevented from being covered by the sealing resin to protrude from the sealing resin in a protruding direction perpendicular to the thickness and transverse directions, and the imaginary plane extends perpendicular to the protruding direction.
