Abstract:
1. A resin member joining method for joining two resin members which are configured to be irradiated with light for optical detection, comprising the steps of: mounting a first resin member having an optical transparency for an incident laser beam on a base board having a supporting surface being an optical mirror surface in such a way that a coating a light absorbing agent capable of absorbing an incident laser beam on a superposing a irradiating a laser beam to the coated light absorbing agent from a wherein the optical mirror surface is a surface having a surface roughness Ra in a range of 5 nm or more and 100 nm or less such that the laser beam is prevented from scattering on the supporting surface and heat generation caused by a scattered laser beam is prevented.
