Electronic device

An electronic device comprising:

• a circuit board which has a continuous through hole and uses a resin comprising an epoxy as a main ingredient and having a glass transition temperature in excess of 150° C. as a base member;
• a metal casing which has an opening;
• a connector which is fitted to the opening of the metal casing;
• and
• a pin of the connector which is connected to the through hole with a conductive member in a state of inserting the pin into the through hole;
• wherein the cross sectional area at the board side end of the pin is smaller than the cross sectional area at the casing side end of the pin.

An electronic device comprising:

• a circuit board which has a continuous through hole and uses a resin comprising an epoxy as a main ingredient and having a glass transition temperature in excess of 150° C. as a base member;
• a metal casing which has an opening;
• a connector which is fitted to the opening of the metal casing;
• and
• a pin of the connector which is connected to the through hole with a conductive member in a state of inserting the pin into the through hole;
• wherein a first center line for a first portion of the pin passing through the board and a second center line for a second portion of the pin passing through the casing are displaced from each other, and
• wherein the first center line is displaced away from a center of the board relative to the second center line.

An electronic device comprising:
