摘要：
A mesh structure portion is provided at a part of a stripe structure IGBT chip, gate resistance of a respective minute IGBT is reduced and in a gate portion chip a filter is constituted by a resistor and a condenser. Under a severe environment such as an integrated ignition coil, a small size and a low cost ignitor which can use without a necessity for a protection circuit by a peripheral circuit can be provided. An ignition apparatus having IGBT which is strong against serge resistant performance and noise resistant performance can be obtained.
