"textContent": "To obtain a thermal flow meter capable of providing thermal insulation without degrading responsiveness of a temperature detection element. A thermal flow meter of the present invention includes an air flow sensing portion that detects a flow rate by performing heat transfer with a measurement target gas passing through the main passage using a heat transfer surface, a temperature detection element that detects a temperature of the measurement target gas, a circuit package obtained by connecting a processing unit that processes signals of the air flow sensing portion and the temperature detection element to a lead and sealing the processing unit using a first molding resin through a first molding process, and a housing where the circuit package is fixed using a second molding resin through a second molding process, wherein, in the circuit package a thickness of a temperature detecting portion for sealing the temperature detection element is thinner than that of a package body portion for sealing the processing unit",
